実験手順

A reaction mixture of 2-(4-chloro-7,8-dihydropyrido[4,3-d]pyrimidin-6(5H)-yl)-5-methylbenzonitrile (80 mg, 0.28 mmol) and (2-isopropylpyrimidin-5-yl)methanamine (60 mg, 0.40 mmol) (prepared similarly according to the method for Intermediate 13) in acetonitrile (1 mL) and N,N-diisopropylethylamine (0.3 mL, 2 mmol) was subjected to microwave irradiation at 185° C. for 3 h. The reaction mixture was concentrated and purified by semi-preparative HPLC (100×20.2 mm, C18 column; 40-60% CH3CN-water [10 mM Et2NH]) to yield a light yellow solid.
