実験手順
To a stirred solution of crude (2E)-1-[2-(allyloxy)-4-methylphenyl]-3-(dimethylamino)prop-2-en-1-one (Step 2, 14.1 g, 57.5 mmol) in methanol (70 mL) was added hydroxylamine hydrochloride (4.4 g, 63 mmol) and the reaction was stirred at room temperature for 1 hour. Colourless needle crystals were filtered off and analysed and found to be the title compound, 7.3 g, in a 58% yield. LCMS (2 min acidic) 1.32 min 64-91% pure by UV, ES+/AP+ 216. 1HNMR (400 MHz, CDCl3) δ ppm 2.40 (s, 3H), 4.67 (m, 2H), 5.35 (dq, 1H), 5.46 (dq, 1H), 6.05-6.20 (m, 1H), 6.77 (m, 1H), 6.82 (s, 1H), 6.88-6.92 (m, 1H), 7.88 (d, 1H).
