Reaction Steps

To a solution of 2,4-dichloro-7-(4-fluorophenyl)-6,7-dihydro-5H-cyclopenta[d]pyrimidine (Preparation H) (90 mg, 0.318 mmol) in MeOH (3179 μL), 4,4-difluoropiperidine (115 mg, 0.95 mmol) was added. The reaction was allowed to stir at rt. When the reaction was complete, removed solvent and applied residue to Silica gel. Eluted with EtOAc/Hex to afford the desired 2-chloro-4-(4,4-difluoropiperidin-1-yl)-7-(4-fluorophenyl)-6,7-dihydro-5H-cyclopenta[d]pyrimidine (80.8 mg, 0.220 mmol, 69.1% yield). LC-MS (M+H)+=368.0.
