59702-07-7, 1-Methylpiperazin-2-one is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A solution of 1-methylpiperazin-2-one (198 mg, 1.74 mmol) in dichloromethane (4.00 mL) was added to a stirred solution of methyl 2-chloropyrimidine-5-carboxylate (300 mg, 1.74 mmol) in dichloromethane (4.70 mL) at 25¡ã C. The resulting solution was stirred at room temperature for 4 h under nitrogen. The reaction mixture was concentrated and dissolved in ethyl acetate (25 ml) and NaOH (50 ml, 1M aqueous solution). The organic layer was washed with ethyl acetate (25 ml). The organic layers were combined and washed with brine (50 ml), dried using MgSO4, filtered and evaporated to dryness to afford methyl 2-(4-methyl-3-oxopiperazin-1-yl)pyrimidine-5-carboxylate (246 mg, 57percent) as a cream solid. 1H NMR (399.9 MHz, DMSO-d6) delta 2.91 (3H, s), 3.44 (2H, t), 3.83 (3H, s), 4.09 (2H, t), 4.35 (2H, s), 8.86 (2H, s). MS: m/z 501 (2MH+), 59702-07-7
