Versuchsvorschrift

In a 100 ml flask, fitted with a condenser, 2-(4-isopropylphenyl) propionitrile 1.90 g (11.0 mmol) was dissolved in tetrahydrofuran (70 ml) under a nitrogen atmosphere. Borane-methyl sulfide complex (10.0-10.2 M in tetrahydrofuran, 1.20 ml, 12.1 mmol) was added to the solution and the mixture heated to reflux for 3 hours. The solution was cooled to ambient temperature and a saturated solution of hydrochloric acid in methanol added slowly until a white precipitate formed. The solvent was removed in vacuo and the resulting white solid triturated (×4) with diethyl ether. Drying under vacuo gave 1.76 g (73%) of the title compound.
