Procedure

The compound was prepared by transesterification of 2.9 g (0.01 mol) of 1-benzhydryl-5-methoxycarbonyl-imidazole of Example 8. To this end it was refluxed for some time in 100 cc of propanol and in the presence of catalytic amounts of toluene sulfonic acid. The colorless crystals obtained had a melting point of 81° C.
