Procedure
A solution of compound 54 (0.25 g, 0.25 mmol) and benzoyl-tetrazole (0.09 g, 0.50 mmol) in anhydrous CH3CN (0.5 mL) was stirred in a preheated bath at 65° C. for 1.5 h. After this time, the TLC (10% CH3COCH3/CH2Cl2) that the reaction was complete. The reaction mixture was cooled to room temperature and taken up in EtOAc (30 mL) ,washed with aq saturated sodium bicarbonate solution (2×15 mL) and water (15 mL) dried over anhydrous Na2SO4. Solvent was removed under reduced pressure and the residue was purified by column chromatography on silica gel using 10% CH3COCH3/CH2Cl2 as the eluent and the appropriate fractions were combined and concentrated to give a colorless foam, yield (0.105 g, 50%).
