PROCEDURE
实验过程
To a solution of 7-chloro-5-(4-methoxybenzyloxy)-3-methylpyrido[4,3-d]pyrimidin-4(3H)-one (750 mg, 2.26 mmol) in 1,4-dioxane (11 mL) were added 4-morpholinophenylboronic acid pinacol ester (654 mg, 2.26 mmol), 2M aqueous Na2CO3 solution (3.39 mL, 6.78 mmol), and Pd(dppf)2Cl2 (36.9 mg, 0.045 mmol). The reaction mixture was purged with N2 and heated at 140° C. by a microwave reactor for 15 minutes. The mixture was then cooled, quenched with H2O (100 mL) and extracted with CH2Cl2 (3×50 mL). The combined organic layer was dried over MgSO4 and evaporated under reduced pressure to afford crude 5-(4-methoxybenzyloxy)-3-methyl-7-(4-morpholinophenyl)pyrido[4,3-d]pyrimidin-4(3H)-one.
