실험 절차

A reaction mixture of 5-chloro-2-(4-chloro-7,8-dihydropyrido[4,3-d]pyrimidin-6(5H)-yl)benzonitrile (150 mg, 0.49 mmol) and (S)-2-amino-2-(6-(trifluoromethyl)pyridin-3-yl)ethanol (150 mg, 0.74 mmol) (prepared similarly according to the method for Intermediate 10) in acetonitrile (3 mL) and N,N-diisopropylethylamine (170 μL, 0.98 mmol) was subjected to microwave irradiation at 180° C. for 4 h. The reaction mixture was concentrated and the residue was purified by silica gel column (100% EtOAc and then 0-20% MeOH/CH2Cl2) followed by semi-preparative HPLC (100×20.2 mm, C18 column; 30-70% acetonitrile-water [10 mM Et2NH]) to yield a light yellow foam (44 mg).
