39539-66-7, 4-Methylpiperazine-1-carbonyl chloride is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Example 8; 2-(2-difluoromethylbenzimidazoH-yI)-4-[4-(4-methylpiperaziii-l-ylcarbonyl)piperazin- 1 -y 1] -6-morpholinopy rimidine; Diisopropylethylamine (0.261 ml) was added to a stirred mixture of2-(2-difluoromethylbenzimidazol- 1 -yl)-6-morpholino-4-piperazin- 1 -ylpyrimidine (0.208 g), 4-methylpiperazin-l-ylcarbonyl chloride (0.122 g) and methylene chloride (20 ml) and the resultant mixture was stirred at ambient temperature for 1 hour. The reaction mixture was evaporated and the reaction product was purified using a Waters ‘Sunfre’ preparative reversed-phase column (5 microns silica, 19 mm diameter, 100 mm length) and decreasingly polar mixtures of a 0.1% solution of trifluoroacetic acid in water and a 0.1% solution of trifluoroacetic acid in acetonitrile as eluent. There was thus obtained the title compound (0.085 g); NMR Spectrum: (CDCl3) 2.85 (s, 3H), 3.35-3.43 (m, 2H), 3.45-3.5 (m, 4H), 3.5-3.62 (m, 4H), 3.63-3.73 (m, 8H), 3.75-3.88 (m, 6H), 5.53 (s, IH), 7.35-7.5 (m, 3H), 7.9-7.94 (d, IH), 8.18-8.22 (d, IH); Mass Spectrum: MH-H+ 542., 39539-66-7
As the paragraph descriping shows that 39539-66-7 is playing an increasingly important role.
