[0002] Discovered as a human oncogene in the early 1980s, the Kirstin rat sarcoma virus homolog (KRAS) gene encodes a small, monomeric 21-kDa GTPase and has long been an elusive target for cancer therapeutics (Chang et al., PNAS, 1982, 79:4848-52; McCoy et al., Nature, 1983, 302:79-8). KRAS functions as a molecular switch that promotes cell proliferation by cycling between GTP-bound and GDP-bound states. In the GTP-bound state, KRAS signals proliferation through the RAF-MAPK and PI3K-AKT-MTOR pathways. KRAS then hydrolyzes GTP to GDP with the help of GTPase-activating proteins (GAPs). This GDP-bound state "turns off" KRAS's growth-promoting signaling. KRAS can then be turned "on" again by exchanging GDP for GTP with the help of guanine nucleotide exchange factors such as SOS1 (Cox and Der, Small GTPases, 2010, 1:2-27; Kerk et al., Nat Rev Cancer, 2021, 21:510-525). Blocking this exchange by locking KRAS in the GDP-bound state is a practical way to inhibit its growth-promoting activity.
[0003] The human KRAS gene, encoded on chromosome 12p12.1, is one of the most frequently mutated genes in human cancer (Pylayeva-Gupta et al., Nat Rev Cancer, 2011;11:761-774). Mutations that prevent GTP hydrolysis lock KRAS in an active, GTP-bound state, reprogramming cells for persistent proliferation. KRAS mutations at codon 12, glycine (G) to aspartic acid (D), create the chronically active KRAS(G12D) oncoprotein, which has been observed in 6.8% of cancer cases analyzed by next-generation sequencing (Zhou et al., Pathol Oncol Res, 2020;26:2835-2837). In tumor-type-specific studies, KRAS(G12D) is associated with poor clinical outcomes and is observed in 17% of lung tumors, 14.3% of colorectal tumors, and 48% of pancreatic tumors (Aredo et al., Lung Cancer, 2019, 133:144-150; Olmedillas-Lopez et al., World J Gastroenterol, 2017, 23(39):7087-709; Miglio et al., Pathol Res Pract, 2014, 210:307-11; Gou et al., Br J Cancer, 2020, 22:857-867). Historically, oncogenic KRAS mutations have been considered undruggable (McCormick F, Biochem J, 2019, 476:356-74). However, the discovery of an allosteric pocket in GDP-bound KRAS has enabled the search for small molecule inhibitors (Ostrem et al., Nature, 2013, 503:548-51). The G12D mutation encodes an acidic amino acid residue (D) instead of a small, flexible amino acid residue (G) with only hydrogen side chains, further providing unique chemical site binding space. This change in KRAS protein structure provides a unique space that can be targeted by small molecule drugs that specifically inhibit the oncogenic activity of KRAS(G12D). Therefore, it is desirable to design and develop small molecule drugs that target KRAS(G12D) and have sufficient bioavailability to treat diseases such as cancer. Summary of the Invention

[0055] As used herein, " solid tumor " is understood to mean any pathogenic tumor that can be detected by palpation or imaging diagnostic method as a three-dimensional abnormal growth.Solid tumor is distinct from blood tumors such as leukemia.However, because the cells of blood tumors originate from bone marrow, the tissue that produces cancer cells is solid tissue that can be hypoxic.
[0056] "Tumor tissue" or "tumorous tissue" is understood to refer to the cells, extracellular matrix, and other naturally occurring components associated with a solid tumor.
[0057] The specific dosage and treatment regimen for a particular patient will depend on a variety of factors, including the activity of the particular compound used, age, body weight, general health, sex, diet, time of administration, rate of excretion, drug combination, the judgment of the treating physician, the severity of the particular disease being treated, etc. The amount of a compound described herein in the composition will also depend on the particular compound in the composition.

[0058] chemical synthesis The representative examples presented below are intended to help illustrate the disclosure and are not intended to, and should not be construed as, limiting the scope of the invention. Typical starting materials used were obtained from commercial sources or prepared in other examples unless otherwise noted.
[0059] The compounds claimed herein were prepared according to the procedures outlined in Scheme 1. [ka]
[0060] Preparation of Example 1 Step 1: 2,4,7-Trichloro-8-fluoropyrido[4,3-d]pyrimidine. To a mixture of intermediate 1-1 (50.0 g, 232 mmol, 1.00 equiv.) (150 mL) in toluene (Tol.) was added POCl3 (178 g, 1.16 mol, 108 mL, 5.00 equiv.) at 25 °C. Next, DIEA (65.9 g, 510 mmol, 88.9 mL, 2.20 equiv.) was added to the mixture at below 40 °C. The mixture was stirred at 110 °C for 12 h. LC-MS showed the desired product. The reaction mixture was distilled under reduced pressure to remove POCl3 at 90 °C. The residue was slowly poured into saturated NaHCO3 (maintaining pH = 8). During this time, a yellow precipitate formed. It was collected by filtration and washed with H2O. The solid was used directly in the next step. Intermediate 1-2 (101 g, 400 mmol, 86.2% yield) was obtained as a brown solid. HNMR (DMSO-d6, 400 MHz): δ 8.92-8.86 (m, 1H). LC-MS: m / z 253.9 [M+H] + .
[0061] Step 2: tert-Butyl 3-(2,7-dichloro-8-fluoropyrido[4,3-d]pyrimidin-4-yl)-3,8-diazabicyclo[3.2.1]octane-8-carboxylate. To a mixture of intermediate 1-2 (48.5 g, 192 mmol, 1.00 equiv.) in DCM (485 mL) was added a solution of compound 2a (38.7 g, 183 mmol, 0.950 equiv.) in DCM (120 mL). DIEA (49.7 g, 384 mmol, 66.9 mL, 2.00 equiv.) was then added to the mixture at -40 °C and stirred at -40 °C for 0.5 h under a N atmosphere. LCMS indicated that intermediate 1-2 had been consumed, and the desired product was detected. The mixture was quenched with hydrochloric acid (0.5 M) and the aqueous phase was acidified to pH 6-7. After separation, the organic layer was dried over NaSO. The residue was purified by column chromatography (SiO, TLC: petroleum ether: ethyl acetate = 3:1, R f =0.4, petroleum ether:ethyl acetate = 10:1 to 1:1, R f=0.4). Intermediate 1-3 (120 g, 280 mmol, yield 72.9%) was obtained as a white solid. HNMR (DMSO-d6, 400 MHz): δ9.13-8.98 (m, 1H), 4.67-4.36 (m, 2H), 4.35-4.21 (m, 2H), 3.87-3.50 (m, 2H), 1.85-1.71 (m, 2H), 1.66-1.56 (m, 2H), 1.46 (s, 9H).LC-MS:m / z 428.0[M+H] + .

The resulting mixture was stirred under a nitrogen atmosphere for 1 h. The reaction was quenched with water at 0 °C. The resulting mixture was extracted with CHCl (3 × 10 mL). The combined organic layers were washed with saturated aqueous NaCl (2 × 5 mL) and dried over anhydrous NaSO. The resulting mixture was concentrated under reduced pressure. The residue was purified by silica gel column chromatography eluting with PE / EA (1:1) to give intermediate 1-4 (14.5 g, 62.86%) as a white solid. LCMS (ES, m / z): 494 [M+H]
