Reaction Steps
15.0 g (0.11 mol) of 4-chlorobenzaldehyde, 51.3 g (0.53 mol) of ammonium carbonate and 7.6 g (0.12 mol) of potassium cyanate are stirred in 150 ml water and 150 ml methanol for 18 hours at 55° C. The solvent is distilled off, the residue dissolved in water and extracted with ethyl acetate. The combined organic extracts are dried and concentrated by evaporation.
