実験手順

A reaction mixture of 2-(4-chloro-7,8-dihydropyrido[4,3-d]pyrimidin-6(5H)-yl)-5-methylbenzonitrile (160 mg, 0.56 mmol) and (S)-2-amino-2-(6-(trifluoromethyl)pyridin-3-yl)ethanol (118 mg, 0.57 mmol) (prepared similarly according to the method for Intermediate 10) in acetonitrile (2 mL) and N,N-diisopropylethylamine (0.4 mL) was subjected to microwave irradiation at 185° C. for 3.5 h. The reaction mixture was concentrated and the residue was purified by semi-preparative HPLC (100×20.2 mm, C18 column; 40-60% acetonitrile-water [10 mM diethylamine]) to yield a light brown solid.
