Reaction Steps

To about 0.15 mole of α-amino-4-hydroxybenzeneacetic acid dissolved in 700 ml of water and 0.2 mole of glacial acetic acid is added about 0.2 mole of potassium cyanate. The resulting mixture is stirred at room temperature for about 30 minutes. The reaction mixture is saturated with sodium chloride and then extracted with ethyl acetate. The ethyl acetate is washed with water, dried over magnesium sulfate, filtered and evaporated to give α-(aminocarbonyl)amino-4-hydroxybenzeneacetic acid.
