Reaction Steps

To a solution of tert-butyl 2-(4-chlorophenyl)-3-(4-(7-hydroxy-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)piperazin-1-yl)-3-oxopropyl(isopropyl)carbamate (49 mg, 0.09 mmol) in DCM (10 mL) was added HCl in dioxane (4M, 2 mL). The mixture was stirred at room temperature overnight. The solvent was removed to afford the 2-(4-chlorophenyl)-1-(4-(7-hydroxy-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)piperazin-1-yl)-3-(isopropylamino)propan-1-one dihydrochloride (46 mg, 99%). 1H NMR (D2O, 400 MHz) δ 8.38-8.36 (m, 1H), 7.37-7.34 (m, 2H), 7.22-7.19 (m, 2H), 5.18-5.10 (m, 1H), 4.34-4.28 (m, 1H), 4.10-3.00 (m, 12H), 2.50-2.40 (m, 1H), 1.85-1.75 (m, 1H), 1.28-1.26 (m, 6H), 1.20-1.13 (m, 3H). MS (APCI+) [M+H] +444.
