反応手順
Ethyl piperidine-4-carboxylate (3.6 g, 22.9 mmol) was dissolved in benzene (5 mL), and 2,2-dimethylthiirane (5.04 g, 57.3 mmol) was added. The reaction mixture was stirred at 80° C. for 20 hours, poured into water and extracted several times with EtOAc. The combined organic extracts were washed with brine and dried over anhydrous sodium sulfate. The volatiles were evaporated and the residue was dried under vacuum to afford 5.45 g (97%) of the title compound. 1H NMR (300 MHz, CD3OD) δ 4.12 (q, J=7.1 Hz, 2H), 2.92-2.96 (d, J=11.9 Hz, 2H), 2.19-2.40 (m, 6H), 1.61-1.86 (m, 4H), 1.29 (s, 6H), 1.25 (t, J=7.1 Hz, 2H).
