実験手順

The title compound was prepared from 3-(4-amino phenyl)-propan-1-ol (1.02 g, 6.72 mmol) and acrylic acid 2,2,2-trichloroethylester (4.55 g, 22.17 mmol) in the same manner as described for 2-chloro-3-(4-hydroxymethyl-phenyl)-propionic acid methyl ester. The crude product was purified by flash chromatography using DCM/iPrOH 95:5 as the eluent and the product was obtained as an oil (0.74 g, 29.4%). 1H NMR (300 MHz, CDCl3): δ 7.08-7.30 (m, 4H), 4.56-4.60 (t, 1H), 3.63-3.65 (m, 3H), 3.35-3.43 (dd, 1H), 3.18-3.25 (dd, 1H), 2.63-2.68 (m, 3H), 1.84-1.86 (m, 2H).
