Tetrabutylammonium borohydride (750 mg, 2.91 mmol) was added to a solution of 1-(3-phenylbenzofuran-2-yl)ethanone (459 mg, 1.94 mmol) in THF (9 mL) and IMS (1 mL) and the mixture stirred at RT for 1 h. The reaction mixture was quenched by addition of MeOH and volatiles were removed in vacuo. The resulting residue was purified by column chromatography (Si—PCC, gradient 0-40% EtOAc in cyclohexane) affording the title compound as an oil (452 mg, 98%). LCMS (Method C): RT 3.57 min [M-OH]+ 221.1
