実験手順

A solution of 4-ethoxycarbonylmethyl-5-methyl-2-phenylimidazole (19.7 g) in tetrahydrofuran (100 ml) was added dropwise (in 45 min) to lithium aluminium hydride (10 g) in tetrahydrofuran (150 ml). After 2 h refluxing the reaction mixture was allowed to stand overnight at r.t. It was cooled in an ice bath and water (40 ml) and tetrahydrofuran (50 ml) were added. The solids were filtered off and washed with diethylether.
