Reaction Steps

To a solution of Preparation AR [2,4-dichloro-7-(2-chlorophenyl)-6,7-dihydro-5H-cyclopenta[d]pyrimidine] (900 mg, 3.00 mmol) in NMP (Volume: 3.00E+04 μl) was added 2 M monomethanamine (7525 μl, 15.05 mmol). The resulting reaction mixture was stirred at RT for 1 h. Water was added (120 ml) to the mixture and stirred for 30 min. The mixture was filtered to get light green solid which was dried to get 2-chloro-7-(2-chlorophenyl)-N-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-amine (713 mg, 2.424 mmol, 81% yield). LC-MS (M+H)+=295.9. 1H NMR (400 MHz, CD3OD) δ 7.50-7.39 (m, 1H), 7.34-7.19 (m, 2H), 7.04-6.90 (m, 1H), 4.86-4.72 (m, 1H), 3.07 (s, 3H), 2.90-2.67 (m, 3H), 2.11-1.91 (m, 1H).
