Reaction Steps

The N-(4-(2-hydroxyethyl)phenyl)-4-benzyloxycarbonylaminopiperidine (1.38 g, 3.89 mmol) obtained in Example 7 (4) was dissolved in pyridine (7.5 ml), and p-toluenesulfonyl chloride (960 mg, 5.04 mmol) was added thereto under ice-cooling, followed by stirring for 4 hours. Water was added to the reaction mixture, and the precipitate was collected by filtration, thereby obtaining N-(4-(2-tosyloxyethyl)phenyl)-4-benzyloxycarbonylaminopiperidine (1.35 g, 68%) as a yellow solid.
