Abstract
A new activating agent for condensations, 1, 2-benzisoxazol-3-y1 diphenyl phosphate (11, was readily prepared in high yield by the reaction of 1, 2-benzisoxazol-3-01 (2) with diphenyl phosphoiochloridate (3) in the presence of triethylamine in benzene. The reaction of the carboxylic acids with the amines in the presence of 1 was investigated by two procedures, a two-step method and a one-step procedure. Both methods gave the ...
