HCID 23465881HCID 23465881, compound

Procedure

40.26 g (0.18 mol) of (2,6-dichlorophenyl)acetyl chloride and 15 g (0.198 mol) of ammonium thiocyanate are heated for about 10 minutes in 500 ml of acetone. The cooled mixture is filtered, the solid is washed with acetone and the filtrate is evaporated to dryness. Dry ether is added to the oily residue. A yellow crystalline solid is formed and is filtered off. The filtrate is evaporated to dryness. 2,6-Dichlorophenacyl isothiocyanate is obtained in the form of an orange-red oil.
