Versuchsvorschrift

89 mmol of 8-methoxy-4-thiochromanone are dissolved in 70 ml of a mixture of methanol and tetrahydrofuran (3/4). 134 mmol of sodium borohydride dissolved in 50 ml of aqueous methanol (50%) are added. After stirring for 1 hour at room temperature and then extracting with methylene chloride, the resulting product is recrystallised from a mixture of methanol and diethyl ether (1/10).
