Reaction Steps

To a solution of 2,4-dichloro-7-(6-(trifluoromethyl)pyridin-3-yl)-6,7-dihydro-5H-cyclopenta[d]pyrimidine (33 mg, 0.099 mmol) in NMP (Volume: 5 mL) was added methanamine (0.247 mL, 0.494 mmol). The reaction mixture was stirred at room temperature for 2 h. The product was partitioned between ethyl acetate & water. The organic layers were combined and dried in vacuum to afford 2-chloro-N-methyl-7-(6-(trifluoromethyl)pyridin-3-yl)-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-amine (8 mg, 0.024 mmol, 24.64% yield). LC-MS (M+H)+=329.0.
