Versuchsvorschrift
To a solution of 5-fluoroindanone (CAS#700-84-5, 0.942 g, 6.274 mmol) in methanol (15 mL) at 0° C. is added sodium borohydride (0.356 g, 9.411 mmol) in one portion. The cooling bath is removed and after 2 hours, the mixture is poured into water (100 mL) and the volatile organics are removed in vacuo. Extraction with dichloromethane, drying over magnesium sulfate, filtering through a cotton plug and concentration affords 5-fluoro-indan-1-ol, which is used in the next step without further purification.
