To a solution of compound 87A (98 mg, 0.299 mmol) in pyridine (3 ml) was added benzenesulfonyl chloride (0.042 mL, 0.33 mmol). The mixture was stirred at RT overnight, then concentrated. The residue was chromatographed (10 g silica gel) eluting with EtOAc (0-60%) in hexane to give the title compound (140 mg, 93%) as a white foam. HPLC: 99% at 7.06 min (retention time) (Conditions: Zorbax SB C18 (4.6×75 mm); Eluted with 0% to 100% B, 8 min gradient. (A 90% H2O−10% MeOH−0.1% H3PO4 and B=10% H2O−90% MeOH−0.1% H3PO4); Flow rate at 2.5 mL/min. UV detection at 220 nm). MS (ES): m/z 529 [M+Na]+.
