Procedure
20 ml of concentrated hydrochloric acid and 10 ml of Cellosolve are added to 2 g of 4-(2,6-dichlorobenzoyl)-5-hydroxybenzocyclobutene-1-carbonitrile and stirring is carried out for 2 days at room temperature. 100 ml of water are added with stirring and the whole is filtered with suction and recrystallised from ether/hexane. 4-(2,6-dichlorobenzoyl)-5-hydroxybenzocyclobutene-1-carboxamide is obtained having a melting point of 174°.
