Procedure

To a mixture of EXAMPLE 127B (2.0 g), toluene-2-sulfonyl chloride (1.16 g) in dichloromethane (30 mL) was added DMAP (0.305 g). The mixture was stirred at room temperature overnight. The mixture was diluted with ethyl acetate (300 mL) and washed with saturated aqueous sodium bicarbonate mixture, 3% aqueous HCl, water and brine. After drying over Na2SO4 and filtering, the mixture was concentrated.
