反応手順
36.9 g of sodium glyoxylate are added to 130 ml of water, and 75 g of ammonium acetate and 60 g of phenol are added thereto under stirring. The mixture is stirred at 30° to 35° C. for 48 hours. After the reaction, the crystalline precipitates are collected by filtration under cooling, and then successively washed with water and methanol. 27.2 g of DL-p-hydroxyphenylglycine are thereby obtained as white crystals.
