A solution of 1-(3,4-dichlorophenyl)-1-cyclobutane carbonitrile (70 g) prepared in a similar manner to that described in Example 1 in industrial methylated spirit (200 ml) was mixed with a solution of sodium hydroxide (3.7 g) in water (5 ml) and 30% hydrogen peroxide solution added dropwise. The mixture was heated at 50° C. for one hour and then stirred with 10% palladium on charcoal (0.5 g) for one hour. The mixture was filtered and evaporated to dryness to give 1-(3,4-dichlorophenyl)-1-cyclobutane-carboxamide.
