실험 절차

A mixture of intermediate 59 (0.4 g, 0.00109 mol), N-methylbenzylamine (0.42 mL, 0.00326 mol) and MeOH (0.1 mL) is heated at 95° C. for 2 days. The reaction mixture is cooled to RT, dichloromethane is added and the mixture is purified by chromatography on silica gel; gradient elution with heptane:EtOAc (80:20-75:25) gives 110 mg of the product 81. 1H NMR (CDCl3) δ 7.50-7.20 (m, 6H), 7.10-6.90 (m, 7H), 6.90-6.75 (m, 2H), 5.52 (q, 2H), 4.84 (d, 1H), 4.52 (d, 1H), 2.97 (s, 3H), 1.45 (s, 9H); MS: m/z 442 (M++1).
