Procedure
A solution of 4-(2-hydroxyethyl)-piperidine-1-carboxylic acid tert-butyl ester (Aldrich, 0.50 g, 2.2 mmol), triethylamine (0.91 mL, 6.5 mmol), and methanesulfonyl chloride (0.25 mL, 3.3 mmol) in 10 mL THF were processed as described in Example 1C to give the crude title compound which was used directly in the next reaction.
