반응 단계

Mesyl chloride (106 μL, 1.37 mmol) was added to a stirred solution of tert-butyl 3-(hydroxymethyl)pyrrolidine-1-carboxylate (250 mg, 1.242 mmol) and triethylamine (225 μL, 1.62 mmol) in DCM at 0° C. After 20 min, the reaction mixture was diluted with DCM, washed with brine, dried (sodium sulfate) and concentrated in vacuo to afford the title compound i-14a. 1H NMR (500 MHz, CDCl3): δ 4.19 (m, 2H), 3.20-3.60 (m, 3H), 3.17 (m, 1H), 3.05 (s, 3H), 2.65 (m, 1H), 2.07 (m, 1H), 1.74 (m, 1H), 1.48 (s, 9H).
