실험 절차

The 4-hydroxymethyl-N-(4-nitrophenyl)piperidine (47.3 g, 200 mmol) obtained in Example 4(1) was dissolved in pyridine (300 ml), and p-toluenesulfonyl chloride (45.8 g, 240 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. The obtained solid was dried under reduced pressure, thereby obtaining 4-tosyloxymethyl-N-(4-nitrophenyl)piperidine (72.7 g, 93%) as a yellow solid.
