Procedure

Compound 7 (800 g; 1.44 mol) and dimethylamino pyridine (7.2 g; 0.059 mol), under nitrogen, were added to a 5 L three-necked-round bottom flask cooled in an ice water bath. Anhydrous pyridine (1.8 L) was charged and the mixture was stirred at 10-15° C. until a homogeneous solution was obtained. Propane-1-sulfonyl chloride (308 g; 2.16 mol) was added drop-wise from an addition funnel while keeping the reaction temperature <20° C. and the reaction mixture was stirred at 20-25° C. for 3 h. The reaction mixture was added to a mixture of 2-methyl-THF (7 L) and water (10 L) in a flask and the organic layer was separated, washed with 1N HCl (2 L) followed by brine (2 L), and dried. The residue was azeotroped with toluene to remove the residual water to provide crude compound 9 (1116.4 g) which was used in the next step without purification.
