Reaktionsschritte

3-(1H-Imidazol-4-yl)-5-methoxy-6,7-dimethylindan-1-one (0.53 g) is dissolved in ethanol (30 ml) and 0.3 g of sodium borohydride is added. The mixture is stirred at 35-40° C. for 7 hours. About 20 ml of ethanol is then distilled off and 30 ml of water is added. The solution is extracted with ethyl acetate. The combined ethyl acetate extracts are washed with water, dried with sodium sulfate, and evaporated under reduced pressure. The product is the mixture of cis- and trans-isomers (about 85:15). Crystallization of the product from ethyl acetate gives a cis-isomer, m.p. 184-189° C.
