실험 절차

An aqueous solution (400 ml) of sodium carbonate (31.8 g) and carbobenzoxy chloride (51.2 g) were added to a solution of 2,2-diethoxyethylamine (42.0 g) in ethyl acetate (300 ml) under ice-cooling, and the mixture was stirred for 6 hours. After separating the mixture into layers, the organic layer was washed successively with 0.5N hydrochloric acid, an aqueous sodium bicarbonate solution and an aqueous saturated sodium chloride solution, dried and concentrated to give pale orange oily benzyl 2,2-diethoxyethylcarbamate (78.6 g).
