実験手順
A solution of the above ketone (957 mg, 3.00 mmol), catechol (660 mg, 6.00 mmol) and p-TsOH.H2O (1.14 g, 6.00 mmol) in xylene (20 mL) was heated at reflux using a Dean-Stark apparatus to remove water for 24 hours. Standard work-up and purification gave 4-[2-(4-methoxy-phenyl)-benzo[1,3]dioxol-2-yl]-piperidine as a pale yellow oil (335 mg, 36%).
