Reaction Steps

133 g (0.9 mol) of 50% strength aqueous glyoxylic acid was added dropwise with stirring to 91.2 g (0.6 mol) of (4-chlorophenyl)acetonitrile and 210 g (1.5 mol) of potassium carbonate in 1.2 1 of methanol such that the reaction temperature increased to 35° C. The mixture was stirred at room temperature for 6 h and then filtered, and the residue was washed with methylene chloride and dried under reduced pressure. At room temperature, the crude product was stirred with 3 1 of water for 1.5 h, and the residue was filtered off, washed with water and dried. Yield: 138 g of a solid of m.p. 241-242° C.
