Participants

Reaction Steps

To a stirred solution of the product of Example 105 (141 mg, 0.28 mmol) in dichloromethane (10 mL) was added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (104 mg, 0.54 mmol), dimethylaminopyridine (66 mg, 0.57 mmol) and acetic acid (0.035 mL, 0.58 mmol). The mixture was stirred for 18 hours, diluted with ethyl acetate (20 mL), washed with 2N aqueous hydrochloric acid (20 mL) and brine (100 mL), dried (MgSO4) and evaporated to leave a residue which was purified by column chromatography on silica eluting with ethyl acetate: dichloromethane:iso-hexane 2:1:1, to afford the desired product (90 mg).
