Procedure

A mixture of Example 39H (23.8 mg, 0.050 mmol), pyridine (31.6 mg, 0.80 mmol), and 1-naphthalenesulfonyl chloride (45.3 mg, 0.20 mmol) in acetone (1.5 mL) was stirred at rt for 72 h. The reaction mixture was evaporated in vacuo and partitioned between ethyl acetate and 1 N HCl. The organic phase was separated, dried (MgSO4), filtered, and evaporated in vacuo. The residue was purified by chromatography on silica gel eluting with 99:1 dichloromethane/methanol to provide the title compound (32.0 mg, quant. yield).
