Versuchsvorschrift

1-[1-(2-Methoxy-phenyl)-cyclobutyl]-2-[3-(4-trifluoromethyl-phenoxymethyl)-piperidin-1-yl]-ethanone (15 mg) was dissolved in 2 mL of dry methanol and solid sodium borohydride (10 equiv.) was added in portions. Water (5 mL) was added and the mixture was extracted with ether and the ether extracts were concentrated in vacuo and purified on silica gel to give the desired 1-[1-(2-methoxy-phenyl)-cyclobutyl]-2-[3-(4-trifluoromethyl-phenoxymethyl)-piperidin-1-yl]-ethanol (9 mg, 60%). Data for this mixture of diastereomeric amino alcohols: MS 464 (M+1); 1H NMR (300 MHz, CDCl3) partial: δ 6.8-7.6 (m, 8H), 3.85-3.95 (m, 2H, methylene adjacent to aryl ether), the 53.09 singlet for the starting material was absent.
