A process for preparing acyl amide compounds is described, in which a recrystallized o-nitrophenoxy carbonyl compound is hydrogenated with hydrogen gas in the presence of a nickel sponge metal catalyst with ring closure to form a benzoxazine, which is then reacted with an acyl halide to give the corresponding acyl amide compound.
