Abstract

Phenacyl benzoates attract commercial importance due to their various applications in the field of synthetic and photo-chemistry. They play vital role as protecting groups for carboxylic acids in organic synthesis. These are also the photosensitive blocking groups with the ease of cleaving under mild conditions. Amino derivatives of 4- chlorophenacyl benzoate (2a-c) are synthesized by reacting 4-chlorophenacyl bromide with ortho-, meta- and paraamino substituted benzoic acids separately using a slight excess of potassium carbonate in N,N-dimethyformamide medium at room temperature. These reactions offered convenience, mild conditions, high purity and good yield
