Brief introduction of 74879-18-8

As the paragraph descriping shows that 74879-18-8 is playing an increasingly important role.

74879-18-8, (S)-(+)-2-Methylpiperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

74879-18-8, To (S)-2-methyl piperazine (0.150 g, 1.5 mmol) was added 4-bromobenzotrifluoride (0.225g, 1.0 mmol), dichloro-bis(tri-o-tolyphosphine) palladium (II) (0.236 g, 0.3mmol), and sodium t-butoxide (0.144 g, 1.5 mmol), and toluene (2 mL) sequentially. After nitrogen was bubbled through the mixture for 15 minutes, the reaction was heated to lOO’C. The reaction was stirred at 1000C for 2 hr. The reaction was filtered through celite and concentrated under reduced pressure. The residue was then purified on a 1000 micron preparative thin layer chromatography plate eluting with 5% MeOH in dichloromethane to yield the title compound as an oil. IH NMR (500 MHz, CDCl3) delta 7.5 (d, 2H, J=8.7Hz), 6.95 (d, 2H, J = 8.7 Hz), 3.71 (d, 2H, J=IOHz), 3.20 (m, IH), 3.04 (m, 2H), 2.85 (m, 1H),2.48 (m, IH), 1.24 (d, 3H, J=7.2Hz). LC/MS 247 (M+l); HPLC 2.41 min
