実験手順

To a solution of (S)-1-{1-[(4-chloro-2-cyanoquinolin-7-yl)methyl]-1H-1,2,3-triazol-4-yl}-1-(trifluoromethyl)propyl 4-nitrobenzoate (900 mg, 1.65 mmol), tributyl (1-ethoxyvinyl)tin (0.6 ml, 1.73 mmol) in dioxane (6 mL) was added lithium chloride (210 mg, 4.96 mmol) and Pd(PPh3)4 (95 mg, 0.083 mmol). The reaction mixture was stirred at 100° C. overnight then cooled to room temperature. The solution was then diluted with ethyl acetate, washed with sat. sol. of ammonium chloride, brine and dried over magnesium sulfate. The crude material was purified on silica gel (eluting solvent: 3% acetone in CH2Cl2) to afford the title compound. 1H NMR (400 MHz, acetone-d6): δ 8.52 (s, 1H), 8.42 (d, 2H), 8.39 (d, 1H), 8.30 (d, 2H), 8.05 (d, 1H), 7.95 (s, 1H), 7.75 (dd, 1H), 6.02 (s, 2H), 4.75 (dd, 2H), 4.12 (q, 2H), 3.05 (m, 1H), 2.85 (m, 1H), 1.40 (t, 3H), 1.15 (t, 3H).
