Reaction Steps

4-Bromo-6-(5-chloropyridin-2-yl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine (25 mg, 0.077 mmol), (S)-1-(6-(trifluoromethyl)pyridin-3-yl)ethanamine (73.0 mg, 0.384 mmol), N,N-diisopropylethylamine (40.1 μL, 0.230 mmol), and acetonitrile (1.0 mL) were added to a 0.5 to 2 mL microwave vial. The mixture was reacted in the microwave reactor for 2.5 hrs at 200° C. The resulting mixture was treated with CH2Cl2 and washed with 1 M NaH2PO4, dried (Na2SO4), and evaporated. The residue was purified by silica gel column to obtain a light yellow solid (18.6 mg).
