Procedure
Benzenesulphonyl chloride (10 ml) was added to a stirred solution of 6-aminocaproic acid (8.8 g) in 10% sodium hydroxide solution (50 ml) over 30 minutes. The solution was stirred for 1 hour, acidified with dilute hydrochloric acid and the precipitate was collected by filtration. Recrystallisation from chloroform yielded 6-(benzenesulphonamido)hexanoic acid (10.5 g) as white prisms. m.p. 119°-120° C.
