反応手順

A reaction mixture of 2-(4-chloro-7,8-dihydropyrido[4,3-d]pyrimidin-6(5H)-yl)-5-methylbenzonitrile (400 mg, 1.41 mmol) and (2-methylpyrimidin-5-yl)methanamine (400 mg, 3.25 mmol) in acetonitrile (3 mL) and N,N-diisopropylethylamine (1.5 mL, 8.6 mmol) was subjected to microwave irradiation at 185° C. for 2.5 h. The reaction mixture was concentrated and purified by preparative HPLC (100×20.2 mm, C18 column; 40-60% CH3CN-water [10 mM Et2NH]) to yield a light brown solid.
