Procedure

To a mixture of the compound obtained in step f above (409 mg, 1.020 mmol), NMM (0.4 mL, 3.58 mmol) and HOBt (234 mg, 1.734 mmol) in DMF (10 mL) at −15° C. was added EDCl (214 mg, 1.123 mmol). After the reaction was stirred for 30 minutes, it was allowed to warm to room temperature, BnONH2HCl (179 mg, 1.123 mmol) was then added and the reaction was stirred overnight. The solvent was removed under vacuum; the residue was diluted with EtOAc and washed with brine. The combined organic layers were dried and concentrated; the crude product was purified by silica gel column chromatography which gave the title compound as an oil (426 mg, 83% yield).
