The general procedure for the synthesis of 2-formamidoacetic acid from formic acid and glycine was as follows: formic acid (140 mL, 3.71 mol) was reacted with acetic anhydride (47 mL, 0.50 mol) with stirring for 1 hour at 45 °C. Subsequently, glycine (0.05 mol) was added to the reaction mixture and stirring was continued at room temperature for 24 hours. After completion of the reaction, the mixture was evaporated to dryness to afford the target product 2-formamidoacetic acid.
