Procedure

A solution of Example 23 (0.138 g, 0.28 mmol) in DCM (6 mL) was treated with methanesulphonamide (0.1 g, 1.0 mmol 1), 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide hydrochloride (0.2 g, 1.0 mmol) and 4-(dimethylamino)pyridine (0.033 g, 0.28 mmol) and the mixture was heated to reflux for 3 days. The reaction mixture was concentrated in vacuo and the crude residue was partitioned between DCM (20 mL) and water (10 mL). The organic layer was concentrated in vacuo, and the crude residue purified by FCC on silica gel (eluting with 0-10% MeOH/DCM), to give the title compound (38 mg, 24%) as a white solid. HPLC-MS (pH 10): MH+ m/z 571.7 [M+H]+, RT 1.49 minutes.
