Application of 1240390-28-6, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.1240390-28-6, name is 2,4-Dichloropyrimidine-5-carboxylic acid amide, molecular formula is C5H3Cl2N3O, molecular weight is 192.0028, as common compound, the synthetic route is as follows.
4-(tert-Butylamino)-2-chloropyrimidine-5-carboxamide A mixture of 2,4-dichloro-pyrimidine-5-carboxamide (10.0 g), DIPEA (11 mL) in NMP (30 mL) were stirred at 25 C. tert-Butylamine (6.6 mL) was charged to the mixture, and the mixture was stirred at 25 C. for 16 h. Water (100 mL) was added to the mixture at 25 C. The mixture was stirred for 1 h. The suspension was filtered, washed with water (50 mL) and dried in a vacuum oven at 40 C. with a nitrogen bleed for 24 h to give 4-(tert-butylamino)-2-chloropyrimidine-5-carboxamide as a white solid (8.7 g, 84%). 1H NMR (DMSO-d6) delta 9.41 (s, 1H), 8.55 (s, 1H), 8.19 (s, 1H), 7.67 (s, 1H), 1.42 (s, 9H).
Statistics shows that 1240390-28-6 is playing an increasingly important role. we look forward to future research findings about 2,4-Dichloropyrimidine-5-carboxylic acid amide.
