5464-12-0,5464-12-0, 1-(2-Hydroxyethyl)-4-methylpiperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a solution of the acid of example 1 (20 mg, 0.015 mmol), triethylamine (6.3 DL, 0.045 mmol), and 4-dimethylaminopyridine (catalytic amount) in dichloromethane (1 mL) was isopropenylchloroformate (5DL, 0.045 mmol) at room temperature. After 5 minutes, l-(2- hydroxyethyl)-4-methylpiperazine (43 mg, 0.15 mmol) was added. The reaction mixture was stirred at room temperature for 3 hours. The solvent was evaporated, and the residue was purified on preparative reversed-phase HPLC. The product was obtained as a light yellow solid after lyophilization. 1H NMR (CD3OD5 500MHz): d 8.61 (d, J=9.5, 1 H), 8.57 (m, 2 H)3 8.43 (s, 1 H), 8.18 (S5 1 H)5 8.14 (d5 J=Il.
