109-07-9, 2-Methylpiperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Example 11 An experiment was carried out as described for Example 9, except that 45.55 g of 1-butanol and 4.61 g of water (water content 9.2 wt%) were used instead of 50.00 g of 1-butanol. As a result, the conversion of 2-methylpiperazine was 94.3%, and the selectivity of 1-tert-butoxycarbonyl-3-methylpiperazine was 85.8% (reaction yield 80.9%).Comparative Example 8 An experiment was carried out as described for Example 9, except that 37.56 g of 1-butanol and 12.67 g of water (water content 25.2 wt%) were used instead of 50.00 g of 1-butanol. As a result, the conversion of 2-methylpiperazine was 81.6%, and the selectivity of 1-tert-butoxycarbonyl-3-methylpiperazine was 70.9% (reaction yield 57.9%).Comparative Example 9 An experiment was carried out as described for Example 9, except that 25.00 g of 1-butanol and 25.00 g of water (water content 50.0 wt%) were used instead of 50.00 g of 1-butanol. As a result, the conversion of 2-methylpiperazine was 81.2%, and the selectivity of 1-tert-butoxycarbonyl-3-methylpiperazine was 41.8% (reaction yield 33.9%).
109-07-9 2-Methylpiperazine 66057, apiperazines compound, is more and more widely used in various.
