4318-42-7, 1-Isopropylpiperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Example 13 Preparation of 4-(4-Isopropyl-piperazin-1-yl)-2-methyl-7-nitro-2,3-dihydro-isoindol-1-one To a suspension of 4-fluoro-2-methyl-7-nitro-2,3-dihydro-isoindol-1-one (5.0 g, 24 mmol) and potassium carbonate (3.32 g, 24 mmol), triethylamine (6.7 mL, 28.8 mmol) in dimethylsulfoxide (50 mL), 1-isopropyl piperazine (4.1 mL, 28.8 mmol) is added and the mixture is stirred at 60¡ã C. for 4 hours. The mixture is poured into iced water, and the resulting brown solids are collected by filtration and dried in vacuo at 50¡ã C. to afford 4-(4-Isopropyl-piperazin-1-yl)-2-methyl-7-nitro-2,3-dihydro-isoindol-1-one as brown solids in 91percent yield. Rf=0.14 (AcOEt). 1H-NMR (400 MHz, CDCl3, delta, ppm): 1.09 (s, 3H), 1.11 (s, 3H), 2.70 (t, 4H), 2.80-2.74 (m, 1H), 3.19 (s, 3H), 3.21 (t, 4H), 4.37 (s, 2H), 7.01 (d, 1H), 7.78 (d, 1H).
4318-42-7, The synthetic route of 4318-42-7 has been constantly updated, and we look forward to future research findings.
