Versuchsvorschrift

To a solution of 3-(3,5-difluorophenyl)-2-[2′-(3-methoxypropyl)-3-methylbiphenyl-4-yl]propanenitrile from step 3 (1 eq.) in THF (0.1M) was added borane-dimethyl sulfide complex (5 eq.). The mixture was refluxed for 5 h without a condensor to release the dimethylsulfide. The final concentration was 0.2M. The mixture was cooled to room temperature, quenched slowly with HCl (1N). The pH was set to 10 using NaOH (1N) and finally the mixture was extracted with CH2Cl2. The organic extract was dried over Na2SO4 filtered and concentrated. Purification by column chromatography on silica gel eluting with CH2Cl2/MeOH(NH3; 2M) 5% afforded the desired compound as a colorless oil. 1H NMR (500 MHz, CD3OD): δ 7.42 (d, 1H), 7.30-7.26 (m, 2H), 7.23-7.20 (m, 2H), 7.12 (d, 1H), 7.04 (s, 1H), 6.76-6.72 (m, 1H), 6.66-6.63 (m, 2H), 3.53-3.50 (m, 1H), 3.25-3.20 (m, 7H), 3.15 (dd, 1H), 2.88 (dd, 1H), 2.65 (d, 1H), 2.64 (d, 1H), 2.12 (s, 3H), 1.70-1.65 (m, 2H).
