실험 절차

A suspension of 26 g of paratoluene sulfochloride in 200 cm3 of water is cooled to 0° C. With stirring there are slowly added 100 cm3 of a 40% aqueous solution of ethylamine in water. At the end of the addition the reaction mixture is again stirred for two hours at 0° C., then for two hours at ambient temperature. The solid in suspension is filtered, washed several times with water, then dried under reduced pressure. 24 g of N-ethyl(4-methyl phenyl) sulfonamide are obtained.
