Participants

Reaction Steps

A solution of 2,4-dichloro-7-(3,4-difluorophenyl)-6,7-dihydro-5H-cyclopenta[d]pyrimidine (421 mg, 1.398 mmol), methanamine, HCl (283 mg, 4.19 mmol) and DIPEA (1.465 mL, 8.39 mmol) in methanol (10 mL) was stirred at rt for 1 h. The solvent was removed in vacuum and the crude product was purified by column chromatography on silica gel to afford 2-chloro-7-(3,4-difluorophenyl)-N-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-amine (154 mg, 0.521 mmol, 37.2% yield). LC-MS (M+H)+=296.2.
