Benzylamine → 4-Benzylamino-6-(1,2,2-trichlorovinyl)-1,3-benzenedi-sulfonamide

Participants

Reaction Steps

A mixture of 0.31 g. of 4-bromo-6-trichlorovinyl-1,3-benzenedisulfonamide and 0.76 ml. of benzylamine is stirred at 100° C for 2 hours and then added to 25 ml. of aqueous acetic acid and cooled in ice. A precipitate is collected by filtration which weighs 0.26 g. after drying, which gives after recrystallization from a ethylacetate/benzene/petroleum benzene mixture 0.17 g. of 4-benzylamino-6-(1,2,2-trichlorovinyl)-1,3-benzenedisulfonamide with m.p. 188°-190° C.
