Procedure

A solution of 0.330 g (0.71 mmol) of methyl (1RS,2RS,3RS,5SR)-4'-[3-(4-chloro-phenyl)-8-aza-bicyclo[3.2.1]oct-2-yloxy-methyl]-biphenyl-2-carboxylate in 10 ml of ether was slowly added dropwise to a suspension of 33 mg of lithium aluminium hydride in 5 ml of ether and the mixture was stirred at room temperature for 4 hours. After the addition of aqueous ether and subsequently water the phases were separated, the organic phase was washed with saturated sodium chloride solution, dried over sodium sulphate, filtered and evaporated. The residue was chromatographed on silica gel using a 140:10:1 mixture of methylene chloride, methanol and ammonia as the eluent. There was obtained 0.210 g (68% of theory) of [4'-[3-(4-chloro-phenyl)-8-aza-bicyclo[3.2.1]oct-2-yloxymethyl]-biphenyl-2-yl]-ethanol as a colourless foam, Rf : 0.18 (methylene chloride:methanol:ammonia=140:10:1), MS: 434 (M+H)+.
