109-07-9, 2-Methylpiperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
109-07-9, 2-Methylpiperazine (3.19 g) was added at 0°C to 2-(tert-butylcarbonyloxyimino)-2-phenylacetonitrile (7.87 g) in tetrahydrofuran (100 mL), and the mixture was stirred for 2 hours. The reaction solvent was removed under reduced pressure, and the residue was purified through silica gel column chromatography (chloroform – 7N ammonia/methanol), to thereby give the title compound as an oil (5.70 g, 89percent). 1H-NMR(400MHz,CDCl3)delta:1.05(3H,d,J=6.4Hz), 1.46(9H,s), 2.40 (1H,br), 2.65-2.84(3H,m), 2.90-3.00 (1H,br), 3.94(2H,br). MS(ESI)m/z:201(M+H)+.
As the paragraph descriping shows that 109-07-9 is playing an increasingly important role.
