반응 단계
A mixture of intermediate 59 (0.5 g, 1.36 mmol), 2-fluorophenethylamine (0.531 mL, 4.07 mmol) and MeOH (0.1 mL) is heated at 100° C. for 3 days. The reaction mixture is cooled to RT, and is purified by chromatography on silica gel; gradient elution with heptane:EtOAc (70:30-60:40) gives 0.27 g of the product 91. 1H NMR (CDCl3) δ 7.40-6.85 (m, 13H), 6.80-6.65 (m, 2H), 5.45-5.25 (m, 2H), 3.90-3.60 (m, 2H), 1.15 (s, 9H); MS: m/z 460 (M++1).
