Reaction Steps

4-[2,2,2-Trifluoro-1-(triethylsiloxy)ethyl]piperidine (303 mg, 1.02 mmol) was dissolved in dichloromethane (6 mL). To this, triethylamine (0.213 mL, 1.53 mmol) and methyl chloroformate (0.213 mL, 1.53 mmol) were added at 0° C. and the mixture was stirred at room temperature for 1 hour. The reaction was stopped by addition of water to the reaction mixture, and extraction with dichloromethane was performed, followed by drying over anhydrous sodium sulfate. The solvent was evaporated off under reduced pressure, and the residue was purified by silica gel column chromatography (hexane/ethyl acetate=17/3) to give 1-methoxycarbonyl-4-[2,2,2-trifluoro-1-(triethylsiloxy)-ethyl]piperidine (287 mg, yield: 79%).
