Reaction Steps

To a solution of 27.4 g. (0.15 mole) of 6-amino-3-chloro-4-methoxybenzonitrile in 150 ml. of 1,2-dichloro-ethane at 0°-5° C. is added with stirring a mixture of 23 g. (0.2 mole) thiophosgene, 100 ml. 1,2-dichloroethane, 20 g. (0.2 mole) calcium carbonate and 200 ml. of water. After the addition the mixture is stirred for one hour at 0°-5° C., warmed to 20° C. and stirred for 6 hours at this temperature and finally at 35° C. for an hour. The reaction mixture is filtered and the organic layer separated, washed with dilute hydrochloric acid, water and dried (MgSO4). The solvent is removed by evaporation and the residue used without purification in the next step.
