In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact.39093-93-1, Thiomorpholine 1,1-dioxide it is a common compound, a new synthetic route is introduced below., 39093-93-1
Example 224-(1,1-Dioxo-thiomorpholine-4-carbonyl)-2-methyl-2H-pyrazole-3-carboxylic acid (2-phenyl-[1,2,4]triazolo[1,5-a]pyridin-7-yl)-amideA mixture of 1-methyl-5-(2-phenyl-[1,2,4]triazolo[1,5-a]pyridin-7-ylcarbamoyl)-1H-pyrazole-4-carboxylic acid (100 mg, 276 mumol), thiomorpholine-1,1-dioxide (44.8 mg, 331 mumol), diisopropylethylamine (145 mul, 828 mumol) and propylphosphonic anhydride (50percent in ethyl acetate, 407 mul, 690 mumol) in tetrahydrofurane (7.00 ml) is stirred for 4 hours at 70¡ã C. and then for 60 hours at 25¡ã C. under nitrogen atmosphere.The solvent is evaporated and to the residue is added sat. aqueous sodium hydrogencarbonate solution.The mixture is stirred for 20 minutes while a white solid precipitates.The solid is collected by filtration, washed with diethylether and dried affording 4-(1,1-dioxo-thiomorpholine-4-carbonyl)-2-methyl-2H-pyrazole-3-carboxylic acid (2-phenyl-[1,2,4]triazolo[1,5-a]pyridin-7-yl)-amide (112 mg, 84.7percent) as a white solid. mp.: >250¡ã C. MS: m/z=480.2 (M+H+).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. 39093-93-1. We look forward to the emergence of more reaction modes in the future.
