Versuchsvorschrift
To a solution of dibenzo[b,d]furan-2-carbaldehyde (191 mg, 973 μmol) in THF (10 mL) in a 50 mL round-bottomed flask equipped with a magnetic stirrer was added NaBH4 (37 mg, 0.978 mmol) and the mixture was stirred for 2 h at RT and quenched by adding 10 mL of a 1 N aq. HCl solution. The reaction mixture was stirred at RT for 20 min and extracted with CH2Cl2 (2×50 mL). The organic phase was washed with water (10 mL), brine (10 mL), dried over Na2SO4, filtered and concentrated at 40° C. under vacuum to afford dibenzo[b,d]furan-2-ylmethanol CCH 34116 as an off-white solid (192 mg, 100% yield).
