Participants

Reaction Steps

A solution of 5.83 g of N-(4-benzyloxybenzyl)-glycine ethyl ester, 0.86 mL of formic acid, and 20 mL of xylene was refluxed for 2 hours using a Dean-Stark trap to remove the water produced in the reaction. After cooling, the reaction mixture was washed with 20% aqueous formic acid, water, saturated sodium bicarbonate solution, water, and brine. Finally the mixture was dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated to furnish 6.23 g of crude N-(4-benzyloxybenzyl)-N-formyl glycine ethyl ester, used in the following reaction without further purification.
