Procedimiento

The procedures of Example 1(ii iii) were used. From 7.63 g of crude 2-n-butyl-1-(2-chloro-6-fluorophenyl)methyl-1H-imidazole was obtained 2.8 q of 2-n-butyl-1-(2-chloro-6-fluorophenyl)methyl-5-hydroxymethyl-1H-imidazo le; mp 106°-108° C. (from ethyl acetate). This material was oxidized with manganese dioxide and worked up as described to give 0.88 g (63%) of 2-n butyl-2-(2-chloro-6-fluorophenyl)methyl-1H-imidazol-5-carboxaldehyde; mp 88°-90° C. (from ethyl acetate).
