Versuchsvorschrift
To a pre-cooled (ice-water bath) solution of BH3.THF (3.4 eq, 11.8 mL) was added a solution of 5-chlorothiophene-3-carbonitrile (0.5 g, 3.48 mmol) in THF (11.5 ml). The reaction mixture was stirred for 4 hours at room temperature and subsequently 6 N HCl (17 ml) was added slowly followed by H2O/MeOH (17/114 mL). The reaction mixture was stirred overnight. Removal of the volatiles afforded the title product (1.0 g) as an off-white solid.
