The solution was treated with (3-dimethylamino-propyl)-ethyl-carbodiimide (EDC) (54 mg, 0.28 mmol). After 1 h, thin layer chromatography indicated complete conversion. The reaction mixture was quenched with 10 mL 1 M HCl(aq) and 30 mL dichloromethane. The phases were partitioned, and the aqueous phase extracted with 5 mL dichloromethane. The organic phases were combined and sequentially washed with 10 mL portions of 0.1 M HCl(aq), saturated. NaHCO3(aq) and brine. The organic layer was dried using Na2SO4, filtered and concentrated. The resulting 31 mg of off-white solid was chromatographed over SiO2 (5% methanol/dichloromethane) to yield 21 mg (31%) of the titled compound. ESI-MS z/z 397 (MH+), 395 (M-H-).
