Abstract
N-succinimidyl haloacetyl aminobenzoates are formed by: (a) reacting an aminobenzoic acid with haloacetylhalide to form a haloacetylaminobenzoic acid; (b) optionally converting the haloacetylaminobenzoic acid from (a) to the ultimately desired halo intermediate compound; (c) reacting the compound from (b) with oxalyl halide to form the corresponding benzoyl compound; and (d) coupling the benzoyl compound from (c) with an N-hydroxysuccinimide to form the ultimately desired N-succinimidyl haloacetyl aminobenzoate.
