2-(p-Aminophenyl)-5-bromo-4-methyloxazole (XIII) and 4-bromo-, 4-iodo-5-methyl-2-sulfanilamidoisoxazole (VII, XVII) were synthesized by direct bromination or iodination of 2-(p-acetamidophenyl)-4-methyloxazole (XII) and 5-methyl-3-(N4-acetylsulfanilamido) isoxazole (XIV), followed by deacetylation, in good yield.
