Abstract

N-ethyl methane sulphonamide is prepared by reacting methane sulphonyl chloride with ethylamine. N - (b -Hydroxyethyl)methane sulphonamide is prepared similarly. p-Carboxy-benzene sulphonamide is prepared by reacting p-cyanobenzene sulphonyl chloride with ammonia and hydrolysing. The p-cyanobenzene sulphonyl chloride is prepared by reacting cyanobenzene with sulphuryl chloride.
