Procedure

To a solution of 4-bromofuran-2-carbaldehyde (500 mg, 2.85 mmol) and morpholine (0.5 mL, 5.71 mmol) in CH2Cl2 (10 mL) was added sodium triacetoxyborohydride (1.2 g, 5.71 mmol). The mixture was stirred at room temperature for 12 hours. The reaction mixture was diluted with EtOAc (100 mL). The organic phase was washed with aqueous NaHCO3 and brine then dried (MgSO4), filtered and concentrated to dryness. The residue was purified by column chromatography (silica, 0-10% MeOH in CH2Cl2) to afford the sub-title compound (600 mg, 86%).
