Reaction Steps

(S)-2-(4-Benzyl-phenoxymethyl)-pyrrolidine (200 mg, 0.658 mmol) was taken into DMF (2 mL), and t-butylbromoacetate (141 mg, 0.724 mmol) was added, followed by potassium carbonate (182 mg, 1.317 mmol). The mixture was heated to 60° C. and left to react overnight. The mixture was diluted with water, and extracted with ethyl acetate (3×). The combined ethyl acetate layers were washed with brine, dried over sodium sulfate, and concentrated to dryness. The compound was then purified by flash chromatography (eluted with 0.5% methanol in dichloromethane with a 40:1 silica ratio) to obtain the title product (161 mg, 0.423 mmol, 64% yield); LCMS; m/z 381.52, found 381 (M); 1H NMR (400 MHz, CDCl3) δ 1.45 (s, 9H), 1.66-1.73 (m, 2H), 1.79-1.85 (m, 2H), 1.99-2.06 (m, 1H), 2.63-2.69 (m, 1H), 3.18-3.22 (m, 2H), 3.40 (d, J=17.2, 1H), 3.59 (d, J 16.8, 1H), 3.79-3.83 (m, 1H), 3.91-3.95 (m, 2H), 6.82 (d, J 8.88, 2H), 7.08 (d, J8.8, 2H), 7.15-7.27 (m, 5H).
