With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.5625-67-2,Piperazin-2-one,as a common compound, the synthetic route is as follows.
To a stirring solution of piperazin-2-one 16 (500 mg, 5.00 mmol) in CH2C12 (5 mL) under argon atmosphere were added triethylamine (1.5 mL, 10.00 mmol) and Boc- anhydride (1.3 mL, 6.00 mmol) at 0 C; warmed to RT and stirred for 18 h. The reaction was monitored by TLC; after completion of the reaction, the volatiles were removed in vacuo. The crude was purified through silica gel flash column chromatography using 2% MeOH/ CH2C12 to afford compound 17 (450 mg, 45%) as pale yellow solid. TLC: 10% MeOH/ CH2C12 (R/. 0.6); 1H-NMR (DMSO-i/tf, 400 MHz): delta 8.02 (br s, IH), 3.81 (s, 2H), 3.48-3.45 (m, 2H), 3.19-3.14 (m, 2H), 1.41 (s, 9H)., 5625-67-2
As the paragraph descriping shows that 5625-67-2 is playing an increasingly important role.
