Reaction Steps

The mixture of the isomers of 4-(3-phenyl-3H-inden-1-yl)-1H-imidazole was hydrogenated in acetic acid at 50° C. using 10% palladium on charcoal as a catalyst. The mixture was filtered through Celite, and the solvent was evaporated. Water was added and the solution was made basic. The water solution was extracted with ethyl acetate. The organic phase was washed with water, dried and the solvent was evaporated. The hydrochloride salt of the product was made in ethyl acetate. The product 4-(2,3-dihydro-3-phenylinden-1-yl)-1H-imidazole was the mixture of the cis and trans diastereomers (the ratio 95:5).
