Procedure

To 40 ml of pyridine were added 3.11 g of the thus obtained 1-(1-chloro-5-isoquinolinesulfonyl)-4-hydroxypiperidine and 3.81 g of p-toluenesulfonyl chloride. The resulting mixture was stirred at a temperature of 15° C. to 20° C. for 24 hours. To the reaction mixture was added 100 g of ice water, followed by extraction twice with 100 ml each of dichloromethane. The dichloromethane layer was dried with anhydrous magnesium sulfate and the dichloromethane was removed under reduced pressure to obtain 4.46 g of 1-(1-chloro-5-isoquinolinesulfonyl)-4-p-toluenesulfonyloxypiperidine.
