Reaction Steps
A solution of {(4-bromophenyl)-[(E)-(3-phenylacryloyl)]amino}acetic acid, methyl ester 1 (14.61 g, 0.39 mol) in THF (150 mL) and methanol (50 mL) was treated with lithium hydroxide (2.80 g, 0.117 mol) in water (50 mL). The reaction mixture was stirred at room temperature for 45 min and then acidified with conc. hydrochloric acid and concentrated in vacuo. The residue was diluted with ethyl acetate and washed with 10% hydrochloric acid, brine, dried (Na2SO4) and the organic solution evaporated to give the title compound as a viscous oil (13.82 g, 97%). 1HNMR (300 MHz) (CDCl3) δ 4.53 (2H, s), 6.36 (1H, d, J=16 Hz), 7.27 (2H, d), 7.3-7.4 (5H, m), 7.60 (2H, d) and 7.76 (1H, d, J=16 Hz).
