'Q illation of an intermediate 4-beneoyloxybenzenesulfonamide (not isolated) arid subsequent hydrolysis of the benzoate linkage. Since some cleavage of the benzoate linkage by the amine was usually observed using this method, later work emphasized the use of excess amine to affect the cleavage quantitatively, thereby eliminating the hydrolysis step; yields, in general, were higher by this method. Data in Table V are for the two-step ...
