Participants

Reaction Steps

Ethanesulfonyl chloride (2.2g., 0.0171 mole) was added dropwise to a stirred solution of 3-methyl-4-aminophenyl N-methylcarbamate (3.0g., 0.0166 mole) in 20 ml. of pyridine. The temperature rose to a maximum of 38° C. and then subsided. Stirring was continued at ambient temperature for one hour, and the reaction mixture poured into excess water to give an insoluble precipitate. Recrystallization from ethanol-water gave the product as a beige powder, m.p. 146.5°-48.5° C.
