実験手順
732 mg (19.2 mmol) of NaBH4 were added in portions, while cooling (ice bath), to a solution of 2.46 g (14.8 mmol) of 1-(phenylthio)propan-2-one in methanol (18 ml). Stirring was then carried out for a further 2 h while cooling (ice bath). The mixture was then quenched with AcOH (17 ml) and then concentrated in vacuo. The residue was taken up in an ether/water mixture and neutralized with NaHCO3. The phases were separated and the organic phase was dried over MgSO4, filtered and concentrated in vacuo. The residue was purified by means of CC (EA/hex 15:85), yielding 1.3 g (7.7 mmol, 52%) of 1-(phenylthio)propan-2-ol.
