Procedure
A mixture of 60 g of N-(p-chlorobenzoyl)glycine, 34.5 g of p-hydroxybenzaldehyde, 23 g of fused sodium acetate and 170 ml of acetic anhydride was heated under reflux for 1 hour. The reaction mixture was cooled slightly and 400 ml of ethanol was added. A solid precipitated on cooling and was filtered and washed with cold ethanol and cold water. An analytical sample was made by recrystallization from CCL4 /EtOH/AcOH, m.p. 185-186.
