Reaction Steps

In 50 ml of methylene chloride was added 15.0 g (35.8 mmol) of glycine ethyl ester hydrochloric acid, followed by addition of 9.2 9 (75.3 mmol) of 4-dimethylaminopyridine under ice-cooling. After stirring for 10 minutes, 6.5 ml (39.4 mmol) of benzyloxyacetylchloride was added dropwise under ice-cooling over 30 minutes. The temperature was raised up to room temperature, and the mixture was stirred for 12 hours. To the mixture, 20 ml of methylene chloride was added, and filtered. To the filtrate, 5% hydrochloric acid was added, and the mixture was extracted with methylene chloride. The extract was washed with saturated brine, dried over anhydrous sodium sulfate, and filtered. The filtrate was concentrated and 9.0 g of N-benzyloxyacetylglycine ethyl ester was obtained (yield 100%).
