反応手順
To a slurry of sodium hydride (47 mg, 60% in mineral oil, 1.2 mmol) in tetrahydrofuran at 0° C. was added 4-fluorothiophenol (0.1 mL, 0.94 mmol). The reaction mixture was warmed to rt. for 20 min, followed by addition of 4-(2-iodoeth-1-yl)-1-tert-butoxycarbonylpiperidine (265 mg, 0.78 mmol, from Step C). The reaction was then heated to reflux for 10 min, cooled and diluted with ether. The organic layer was washed with 1 N NaOH, dried over magnesium sulfate and concentrated to provide 252 mg (95%) of the title compound. ESI-MS: 340.0 (M+H); HPLC A: 4.07 min.
