실험 절차

To a mixture of 4-methoxyphenylboronic acid (1.57 g, 10.36 mmole) and tert-butyl 4-(3-hydroxybenzylidene)piperidine-1-carboxylate (2.5 g, 8.6 mmole) in dichloromethane (75 mL) were added copper acetate (1.63 g, 8.6 mmole), triethyl amine (5.219 g, 51.6 mmol) and molecular sieves. The mixture was stirred at room temperature overnight. The reaction mixture was filtered through celite pad. The filtrate was evaporated and purified by column chromatography to give the title compound (1.1 g, 32%). 1H NMR (500 MHz, CDCl3): δ ppm 7.26 (t, 1H), 6.99 (d, 2H), 6.89 (t, 3H), 6.79 (t, 2H), 6.29 (s, 1H), 3.80 (s, 3H), 3.48 (s, 2H), 3.38 (s, 2H), 2.42 (s, 2H), 2.29 (s, 2H), 1.47 (s, 9H).
