Reaction Conditions

Reaction Steps

Triphenylphosphine (231 mg, 0.883 mmol) was added to a solution of 2-(1-azidoethyl)-3-phenylbenzofuran (186 mg, 0.706 mmol) in THF (9 mL) and water (1 mL). The mixture was heated at 60° C. for 2 h and then cooled to RT. Volatiles were removed under reduced pressure and the resulting residue was purified by column chromatography (Si—PCC, gradient 0-10% MeOH in EtOAc) affording 1-(3-phenylbenzofuran-2-yl)ethanamine as an oil (327 mg, quantitative). LCMS: RT 2.21 min [M−NH2]+ 221.1
