Reaction Conditions

Reaction Steps

To a suspension of Compound 100b (0.25 g, 1.6 mmol) and pyridine (0.40 mL) in dichloromethane was added at 0° C. a solution of para-toluenesulphonyl chloride (0.336 g, 1.76 mmol) in 1 mL of dichloromethane. The reaction mixture was stirred at 0° C. for 30 min., then at r.t. for 3.5 h. Dilution with dichloromethane, washing with 1M aqueous NaHSO4 and brine, drying with Na2SO4, afforded, after evaporation, a crude which was purified by means of automated flash chromatography (SP01®TM-Biotage; gradient Dichloromethane-Methanol from 1:0 to 95:5) to give the title
