반응 조건

반응 단계

To a solution of 1-methyl-2-piperidine-methanol (Aldrich, 0.27 mL, 2.1 mmol) in 10 mL tetrahydrofuran (THF) at 0° C. was added triethylamine (0.87 mL, 6.22 mmol) followed by methanesulfonyl chloride (0.24 mL, 3.1 mmol). The mixture was stirred at 0° C. for 10 min then the ice-bath was removed and the reaction mixture was stirred at 23° C. for an additional 1.5 h. The reaction mixture was filtered though Celite with THF and concentrated under reduced pressure. This crude material was used directly in the next reaction.
