Participants

Reaction Steps

A solution of 2,4-dichloro-7-phenyl-6,7-dihydro-5H-cyclopenta[d]pyrimidine (150 mg, 0.566 mmol) and excess N-methylethanamine (0.486 mL, 5.66 mmol) in MeOH (2 mL) was stirred at rt for 1 h. The solvent was removed in vacuum to afford 2-chloro-N-ethyl-N-methyl-7-phenyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-amine (163 mg, 0.566 mmol, 100% yield). LC-MS (M+H)+=288.2.
