Procedure
A solution of 5 g. of ethyl 4-(11-bromoundecanamido)benzoate in 50 ml. of tetrahydrofuran is slowly added with stirring to 13 ml. of 1 M borane in tetrahydrofuran. The solution is poured into 50 ml. of dilute hydrochloric acid and the resulting mixture is filtered. The solid is crystallized from acetonitrile to yield ethyl 4-(11-bromoundecylamino)benzoate as a white, crystalline solid.
