Procedure

A solution of compound 128 (250 mg, 0.53 mmol) in dry pyridine (2.0 mL) was flushed with argon and cooled to 0° C. 4-Methyl-benzenesulfonyl chloride (102 mg, 0.53 mmol) was added and the reaction was allowed to come to RT overnight under stirring. The reaction mixture was poured into a mixture of EtOAc/water. The organic phase was washed with water, brine, filtered and concentrated in vacuo to give the crude product. The crude product was purified by continuous gradient flash chromatography using EtOAc/petroleum ether (40-60) 25:75 to 50:50 as the eluent to afford the title compound.
