Reaction Steps

To a stirred solution of (S)-cyclopropyl(6-(trifluoromethyl)pyridin-3-yl)methanamine dihydrochloride (0.048 g, 0.17 mmol) and N,N-diisopropylethylamine (96 uL, 0.55 mmol) in acetonitrile (1.8 mL) was added 4-bromo-6-(5-chloropyridin-2-yl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine (0.045 g, 0.14 mmol). The reaction was heated in microwave for 7 hours at 180° C. The mixture was concentrated and the residue was purified by silica gel column followed by semi-prep HPLC to obtain 7.8 mg of white solid.
