참여 물질

반응 단계

To a stirring solution of benzyl 4-hydroxy-1-piperidinecarboxylate (3.55 mL, 23.4 mmol, Aldrich) and Et3N (7.18 mL, 51.5 mmol, Aldrich) in CH2Cl2 (25 mL) at room temperature was added a solution of methanesulfonyl chloride (1.99 mL, 25.8 mmol, Acros) in CH2Cl2 (25 mL) dropwise. The reaction mixture was stirred at room temperature for 1 h and washed with 1N HCl aqueous solution, H2O and brine. The organic layer was dried over Na2SO4 and concentrated in vacuo to yield 7.43 g of the desired product as a yellow oil. MS (ESI) 314 (M+H).
