Abstract
Two intermediates of pharmaceuticals,Methl 3-methyl-4-(1-oxobuthyl) aminobenzoate and Methyl 3-methyl-4-[(1-oxobuthyl)amino]-5-nitrobenzoate,were synthesized from 3-methyl-4-nitrobenzoic acid by esterification,catalytic hydrogenation,acylamination,nitration and refinement. They were characterized by 1H NMR and IR.
