Embodiment 1

[0029] 2,6,8-Trichloro-N-(4-thiamphenyl)phenyl)pyrimido[5,4- d ]pyrimidin-4-amine;

[0030] Add tetrachloropyrimido[5,4- d ]pyrimidine (0.65 g, 2.4 mmol), THF (5 mL) and H 2 O (0.6 mL). 4-Methylthioaniline (0.1 mL, 0.8 mmol) was added at 0 °C and the reaction was stirred at room temperature for 1 h. Join CH 2 Cl 2 (10 mL), mCPBA (0.36 g, 77%, 1.6 mmol) was added at 0°C, and the reaction was stirred overnight at room temperature. CH 2 Cl 2 Diluted, the organic phase was washed with saturated sodium thiosulfate solution, saturated sodium bicarbonate solution and saturated brine, dried over anhydrous sodium sulfate, and the solvent was removed by rotary evaporation, and the crude product was subjected to silica gel column chromatography (petroleum ether: ethyl acetate=5: 1) Purification gave a yellow solid, and the yield of the two-step reaction was 32%. 1 H-NMR (600 MHz, CDCl 3 ) δ (ppm): 9.12 (s, 1H), 8.20-8.00 (m, 4H), 3.10 (s, 3H).

Embodiment 2

[0032] 2,6,8-Trichloro-N-(2-fluoro-4-thiamphenicol)phenyl)pyrimido[5,4- d ]pyrimidin-4-amine;

[0033] Referring to the preparation method of Example 1. 1 H-NMR (600 MHz, CDCl 3 ) δ (ppm): 9.37 (s, 1H), 8.99(t, J = 8.5 Hz, 1H), 7.95-7.80 (m, 2H), 3.13 (s, 3H).

Embodiment 3

[0035] 2,6,8-Trichloro-N-(2-fluoro-4-cyano)phenyl)pyrimido[5,4- d ]pyrimidin-4-amine;

[0036] Referring to the preparation method of Example 1. 1 H-NMR (600 MHz, CDCl 3 ) δ (ppm): 9.37(s, 1H), 8.94(t, J = 8.3, 1H), 7.66(d, J = 8.6, 1H), 7.58(dd, J = 10.4, 1.7, 1H).

Description

technical field [0001] The present invention relates to the field of chemical medicine, and more to a novel pyrimidopyrimidine derivative, a preparation method thereof, a pharmaceutical composition containing the derivative and its use as a therapeutic agent, especially as a GPR119 agonist and in the preparation and treatment of anti-diabetic and metabolic Use of drugs for diseases such as sexually transmitted diseases. Background technique [0002] Diabetes is a disease that seriously threatens human health. Due to long-term high blood sugar, diabetes can cause chronic damage and dysfunction of various organs and tissues, especially eyes, kidneys, heart, blood vessels, and nerves. Diabetes can be divided into type 1 diabetes, type 2 diabetes and gestational diabetes according to different causes. Among them, type 2 diabetes accounts for 90% of the affected population, and islet β-cell dysfunction is the main cause of type 2 diabetes. [0003] Modern pharmacological treatm...
