반응 단계

To a solution of 590 mg. (3 mmole) of N-methylsaccharin and 1.02 g. (6 mmole) of N-(2-pyridyl)chloroacetamide in 3 ml. of dimethylformamide at 40° C. was added 250 mg. (10.3 mmole) of 99% sodium hydride portionwise over a period of one hour. The reaction mixture was allowed to stir at 40° C. for 2.5 hours and was then added to 100 ml. of 5% hydrochloric acid solution and 300 ml. of ice. The precipitate was filtered and dried to give 24 mg.
