实验步骤: A mixture (4-methylpiperazin-1-yl)acetonitrile (400 mg), hydroxylamine (50% aqueous solution, 2.0 mL) and ethanol (10.0 mL), was stirred at room temperature for 18 hours. The reaction mixture was evaporated to dryness to give a crystalline solid that was washed with hexane and dried under vacuum to give N-hydroxy-2-(4-methylpiperazin-1-yl)ethanimidamide (405 mg). 1H-NMR (400 MHz; CDCl3): 5.19 (br s, 3H), 3.00 (s, 2H), 2.75-2.28 (br m, 8H), 2.70 (s, 3H). The reaction mixture was evaporated to dryness to give a crystalline solid that was washed with hexane dried under vacuum

实验步骤: A mixture of 1-methyl piperazine (0.55 mL, 5.0 mmol), potassium carbonate (3.49 g, 25 mmol) and chloroacetonitrile (0.34 mL, 5.6 mmol) in acetonitrile (3 mL) was stirred at room temperature 8 h. The mixture was diluted with diethyl ether and filtered and concentrated to yield the title compound as yellow crystals (536.6 mg, 77% yield). 1H NMR (500 MHz, CDCl3) δ: 3.50 (s, 2H), 2.66 (t, 4H, J=4.58), 2.52 (bs, 4H), 2.33 (s, 3H). filtered concentrated
