Formic acid (50 μL, 1.4 mmol) and EDCI (240 mg, 1.25 mmol) were added, the reaction stirred for 2 hours and the volatiles removed by evaporation under reduced pressure. The residue was dissolved in EtOAc (20 mL), washed with water (2×10 mL), brine (10 mL), dried (MgSO4) and the volatiles removed by evaporation under reduced pressure. The residue was purified by column chromatography (2:1 EtOAc:Hexane) to afford the title compound (175 mg, 89%) as a white foam.
