Reaktionsschritte

To a solution of 9.82 g (50 mmol) of 3-acetylbiphenyl in 80 ml of dry methanol and 80 ml of dry tetrahydrofuran was added 3.36 g (80 mmol) of sodium borohydride portionwise with ice-cooling, and the mixture was stirred for 1 hour. To the reaction solution was added 600 ml of an about 5% aqueous solution of ammonium chloride and the mixture was extracted with tert-butyl methyl ether. The organic layer was dried and concentrated to obtain 9.86 g (49.7 mmol) of 3-(1-hydroxyethyl)biphenyl as an oil.
