Participants

Reaction Steps

To a solution of R)-2-(4-phenylacetyl-phenoxymethyl)-pyrrolidine-1-carboxylic acid tert-butyl ester (40 mg, 0.16 mmol) in TFA (1.0 mL) was added triethylsilane (0.2 mL, 0.9 mmol) at 0° C. The resulting mixture was allowed to warm to rt and stir at rt for 16 h. The mixture was poured onto 20 mL ice-water solution, neutralized with aq NaOH (2N) to pH=6-7, and then extracted with EtOAc (3×20 mL). The combined organic layers were washed with water (2×20 mL) and brine (20 mL) and dried over anhy. Na2SO4. The solvent was removed in vacuo to obtain the crude product which was purified by silica gel flash chromatography to afford the title product (25 mg, 82%); LCMS; 99%, ESI+, Calcd: 281.4. Found m/z: 282.6 M+1). 1H NMR (400 MHz, CDCl3,); δ 1.54-1.61 (m, 1H), 1.74-1.84 (m, 2H), 1.90-1.99 (m, 1H), 2.84-3.07 (m, 6H), 3.49-3.52 (m, 1H), 3.83-3.92 (m, 2H), 6.82 (d, J=8.8 Hz, 2H), 7.07 (d, J=8.8 Hz, 2H), 7.16-7.20 (m, 3H)-7.34 (m, 2H).
