Reaction Steps

To a mixture of 24.95 g 3-(4-bromophenyl)propionic acid, 12.75 g N, O-dimethylhydroxylamine hydrochloride, 27.14 g EDC, and 17.66 g HOBt were added 300 mL DMF and 47.4 mL DIEA. The reaction mixture was stirred at room temperature for 17 hours and then poured into 700 mL ice water, extracted with 5×200 mL EtOAc. The combined EtOAc solution was washed with 200 mL 5% NaHCO3, 4×200 mL water, and 200 mL saturated brine, dried over Na2SO4, and concentrated under reduced pressure to give crude product as a yellow oil. It was purified on silica gel using 35˜55% EtOAc in hexanes to give the title compound as yellowish oil. 1H NMR (CDCl3, 500 MHz) δ 7.40˜7.43 (m, 2H), 7.11˜7.14 (m, 2H), 3.63 (s, 3H), 3.19 (s, 3H), 2.93 (t, J=7.8 Hz, 2H), 2.73 (t, J=7.7 Hz, 2H). LC-MS: 1.77 min. (M+H=272.1/274).
