Reaction Steps

To a solution of 2,4-dichloro-8-(4-(trifluoromethoxy)phenyl)-7,8-dihydro-5H-pyrano[4,3-d]pyrimidine (Preparation AB) (80.7 mg, 0.221 mmol) in MeOH (2210 μL) was added methylamine (1000 μL, 2.0 mmol) (2M in THF). The reaction was allowed to stir overnight. Removed the solvent and applied to silica gel, eluting with an EtOAc/Hex gradient to afford 2-chloro-N-methyl-8-(4-(trifluoromethoxy)phenyl)-7,8-dihydro-5H-pyrano[4,3-d]pyrimidin-4-amine (69.8 mg, 0.194 mmol, 88% yield). LC-MS (M+H)+=360.0.
