실험 절차

To a stirred solution of 2.09 g of acetoamidine hydrochloride in 50 cc of ethanol was added 1.50 g of sodium ethoxide at room temperature and the mixture was stirred for 10 minutes. The resulting suspension was added to 6.1 g of compound D in 50 cc of ethanol and the resulting mixture was heated under reflux for 6 hours. Thereafter, 4.5 g of compound F was obtained in the same manner as for compound E. Yield: 73.7%.
