[0042]

[0043] Add 479mg (20.8mmol) of sodium in batches to 8.6mL (56.8mmol, 9g) of diethyl malonate, stir for 15min, then add 3g (18.9mmol) of 2-chloro-3-nitropyridine in batches, 90 ℃ reaction 7h. Most of the diethyl malonate was distilled off under reduced pressure, then 20 mL of 36% sulfuric acid (weight percent) was added, and the reaction was carried out at 105° C. for 7 h. After the reaction is complete, wash with ether (50mL×2) and ethyl acetate (50mL×2) successively, discard the organic layer, adjust the pH of the aqueous layer to 8-9 with 1N sodium hydroxide solution, and extract with ethyl acetate (50mL×2). 3), dried over anhydrous sodium sulfate, evaporated to dryness under reduced pressure and separated on a silica gel column (petroleum ether / ethyl acetate=5 / 1) to obtain 2.1 g of a light yellow solid (yield: 80.4%). m.p.28~30℃.

Description

technical field [0001] The present invention relates to a novel dual inhibitor of phosphatidylinositol-3 kinase and rapamycin target protein, its preparation method and application, specifically, a pyridopyrrotriazine (Pyrido[3', 2':3,4]pyrrolo[1,2-f][1,2,4]triazine) compound, the preparation method of the compound, and its function as phosphatidylinositol-3 kinase and rapamycin target protein Application of dual inhibitors in preparing medicines for treating phosphatidylinositol-3 kinase-related diseases such as tumors. Background technique [0002] Phosphatidylinositol-3 kinase (PI3K) can specifically catalyze the phosphorylation of the 3-hydroxyl of phosphatidylinositol (PI), generate inositol lipid substances with second messenger functions, and activate various intracellular target proteins , Involved in the proliferation, differentiation, survival and migration of normal cells. Recent studies have shown that the signaling pathway composed of PI3K and its downstream p...
