Slow addition of 4.98 g. (0.03 mole) of 6-amino-o-anisamide to a mixture of 57% NaH (1.32 g., 0.0315 mole) in 50 ml. dimethylformamide was carried out at room temperature. After the evolution of H2 ceased, the mixture was cooled to 3° C. and 2.06 ml. (0.033 mole) of methyliodide was slowly added at 3°-5° C. The temperature was allowed to go up to room temperature and stir for 2 hours. The mixture was concentrated, the residue extracted into ethyl acetate-water, the mixture was basified, and the ethyl acetate layer was washed with water, brine and dried. Concentration gave a tan solid that was crystallized (ethanol), giving 0.45 g (8%) Of 6-amino-N-methyl-o-anisamide m.p. 186°-189° C.
