Reaction Steps

A mixture of 4-chloro-7-(3-chloropyridin-2-yl)-5,6,7,8-tetrahydropyrido[3,4-d]pyrimidine (0.103 g, 0.000366 mol) and 4-(difluoromethoxy)aniline (0.091 mL, 0.00073 mol) in acetonitrile (3 mL, 0.06 mol) was heated via microwave in a sealed tube at 160° C. for 10 minutes. After cooling to room temperature, the mixture was added to saturated sodium bicarbonate and extracted with ethyl acetate. The organic layer was washed with brine and dried over sodium sulfate. Concentrated to leave an oil. The residue was purified by flash chromatography over silica gel (ethyl acetate/hexane gradient 0 to 100%) to give 0.113 g of a light yellow solid.
