Procedure

In a manner analogous to that described in Example 5, starting from 26.6 g of aluminium trichloride, 9.61 g of 5-methoxybenzocyclobutene-1-carboxylic acid methyl ester and 20.95 g of 2,4-dichlorobenzoyl chloride there is obtained 4-(2,4-dichlorobenzoyl)-5-hydroxybenzocyclobutene-1-carboxylic acid methyl ester having a melting point of 99°-100°.
