Procedure: 5.7 ml of thionyl chloride are added at 0° to 3.18 g of allyloxycarbonylaminoacetic acid. At the same temperature, the mixture is then stirred under a protective gas for 2 hours. It is then diluted with absolute toluene and concentrated in a rotary evaporator. IR (CH2Cl2): 3435, 1800, 1725 cm-1. concentrated in a rotary evaporator

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 12 ml of chloroformic acid allyl ester are added dropwise at 0° to a solution of 7.51 g of glycine in 20 ml of water and 44 ml of 5N NaOH solution. The suspension is then stirred for 16 hours at room temperature. After removal of the insoluble material by filtration, the filtrate is diluted with 100 ml of water and washed twice with CH2Cl2. The aqueous phase is adjusted to pH 2 with 4N HCl and extracted twice with CH2Cl2. The combined organic extracts are washed once with brine, dried over MgSO4 and concentrated by evaporation to form the white crystals of the title compound. IR in CH2Cl2 : 3450, 1715 cm-1. After removal of the insoluble material by filtration the filtrate is diluted with 100 ml of water washed twice with CH2Cl2 extracted twice with CH2Cl2 The combined organic extracts are washed once with brine dried over MgSO4 concentrated by evaporation
