Trifluoroacetic acid → HCID 59211968, compound

Participants

Reaction Steps

Trifluoroacetic acid (2 mL) was added to a solution of [(S)-1-(2-{(4-phenoxyphenyl)-[(E)-(3-phenylacryloyl)]amino}acetyl)pyrrolidin-3-yl]carbamic acid, tert-butyl ester 6 (60 mg) in dichloromethane (6 mL). The reaction mixture was stirred at room temperature for 30 min, and then concentrated in vacuo. The residue was dissolved in ethyl acetate, washed with 1M NaOH, (×2), brine, dried (Na2SO4) and evaporated to dryness. The resultant residue was purified by column chromatography on silica gel, eluting with ethyl acetate/methanol/ammonium hydroxide (90:5:5) to give the title compound (10 mg). 1HNMR (300 MHz) (CDCl3) δ 1.6-2.3 (2H, m), 3.15-3.75 (5H, m), 4.40 (2H, m), 6.43 (1H, d, J=16 Hz), 7.02 (2H, d), 7.06 (2H, d), 7.15 (1H, t), 7.25-7.45 (9H, m) and 7.69 (1H, d, J=16 Hz).
