109-07-9, 2-Methylpiperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
1) 3-Methylpiperazine-1-carboxylic acid tert-butyl ester Di-tert-butyl dicarbonate (21.7 g) was added at room temperature to 2-methylpiperazine (10.0 g) in methanol (200 mL), followed by stirring for 24 hours. The reaction solvent was removed under reduced pressure, and the residue was purified by silica gel column chromatography (chloroform – methanol), to thereby give 3-methylpiperazine-1-carboxylic acid tert-butyl ester as an oily product (19.3 g, 96.5percent). 1H-NMR (300MHz, CDCl3) delta: 1.04 (3H, d, J=6.24Hz), 1.46(9H,s), 2.39(1H,br s), 2.70-2.77(3H,m), 2.94(1H,br s), 3.93(2H,br s). MS(FAB)m/z:201(M+H)+.
109-07-9, As the paragraph descriping shows that 109-07-9 is playing an increasingly important role.
