반응 단계
30 g of an aqueous 40% glyoxylic acid solution are added to 70 ml of water, and 37.5 g of ammonium acetate and 22.5 g of phenol are added thereto under stirring. The mixture is stirred at room temperature for 41 hours. The crystalline precipitates are collected by filtration under cooling, and then successively washed with water and methanol. 7.8 g of DL-p-hydroxyphenylglycine are thereby obtained as white crystals. Yield: 28.9%, M.p. 225°-228° C. (decomp.).
