Adding a certain compound to certain chemical reactions, such as: 456-64-4, name is 1,1,1-Trifluoro-N-phenylmethanesulfonamide, belongs to amides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 456-64-4, Formula: C7H6F3NO2S
EXAMPLE 50 3-Methyl-2-[5-(trifluoromethanesulfonamido)pentan-1-ylthio]-1,4,7b-triazacyclopent[cd]indene To a solution of 500 mg (1.82 mmol) of 3-methyl-2-[5-(amino)pentan-1-ylthio]-1,4,7b-triazacyclopent[cd]indene in 30 ml of acetonitrile were added 0.51 ml (3.66 mmol) of triethylamine and 1.302 g (3.66 mmol) of N-phenyltrifluoromethanesulfonamide. The mixture was stirred for two hours at room temperature. The solvent was distilled off. To the residue was added methylene chloride, which was washed with water, and dried over anhydrous magnesium sulfate. The solvent was distilled off, and the residue was purified by column chromatography (eluent: ethyl acetate) to afford 608 mg (82.1%, a pale yellow solid) of the desired compound. NMR(200 MHz,CDCl3)delta: 1.55-1.85(4H,m), 1.97(2H,m), 2.90(3H,s), 3.39(2H,m), 3.50(2H,t,J=7.0 Hz), 7.69(1H,d,J=7.8 Hz), 7.73(1H,d,J=8.0 Hz), 7.95(1H,dd,J=8.0, 7.8 Hz).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 1,1,1-Trifluoro-N-phenylmethanesulfonamide, and friends who are interested can also refer to it.
