89% | With N-ethyl-N,N-diisopropylamine; triphenylphosphine; In tetrahydrofuran; at 0℃; for 0.5h; | To a solution of methyl (E)-3-(4-hydroxy-3-methoxyphenyl)prop-2-enoate (2.00 g, 9.61 mmol, 1.0 equiv.), l-methylpyrrolidin-3-ol (1.17 g, 11.5 mmol, 1.2 equiv.) andtriphenylphosphine (3.02 g, 11.53 mmol, 1.20 equiv.) in tetrahydrofuran (10 mL) at 0°C was added diisopropylazodicarboxylate (2.33 g, 11.5 mmol, 1.2 equiv.) over 30 minutes. The reaction mixture was diluted with IN hydrochloric acid (50 mL) and extracted with ethyl acetate (3 x 50 mL), the aqueous layer was adjusted to pH = 8 with IN sodium hydroxide solution and extracted with ethyl acetate (3 x 50 mL). The combined organic layer was washed with brine (50 mL), dried over sodium sulfate and concentrated in vacuo to give the desired product as a yellow oil (2.50 g, 89percent) which was used without further purification; 1H NMR (CDC13, 400 MHz) delta7.62 (d, J = 16.0 Hz, 1H), 7.05 (d, = 8.0 Hz, 1H), 7.04 (s, 1H), 7.76 (d, = 8.0 Hz, 1H), 6.30 (d, = 16.0 Hz, 1H), 4.89 - 4.85 (m, 1H), 3.87 (s, 3H), 3.79 (s, 3H), 2.95 - 2.92 (m, 1H), 2.80 - 2.76 (m, 2H), 2.55 - 2.53 (m, 1H), 2.39 (s, 3H), 2.38 - 2.35 (m, 1H), 2.05 - 2.01 (m, 1H). |
