YieldReaction ConditionsOperation in experiment
45% With tetrabutyl ammonium fluoride; triethylamine In tetrahydrofuran at -78 - 60℃; for 2.16667h; 38 Combine 5-trimethylsilanylethynyl-nicotinonitrile (1. 30 g, 11. 5 mmol), (prepared as described in PREPARATION 3), 2-fluoro-5-iodobenzaldehyde (3. 45 g, 13. 8 mmol, (prepared essentially as described in Tet. Lett., 33, 7499, (1992)), bis (triphenylphosphine) palladium (II) dichloride (404 mg, 0. 575 mmol), copper (I) iodide (219 mg, 1. 15 mmol), and triethylamine (22. 4 mL, 161 mmol) in tetrahydrofuran (9 mL). Cool the suspension to-78 °C and treat with a 1. 0 M solution of tetrabutylammonium fluoride (11. 5 mL) in tetrahydrofuran. After 10 min, heat to 60 °C for 2 h. Cool to room temperature and filter through diatomaceous earth washing with ethyl acetate. Purify the crude product by silica gel chromatography, eluting with a gradient from 80 : 20 to 60 : 40 hexanes : ethyl acetate, to give the title compound as an off-white crystalline solid (1. 3 g, 45%). 1HNMR (400 MHz, DMSO-d6) 6 7. 51 (dd, J = 10. 5, 8. 8 Hz, 2H), 7. 93 (ddd, J = 8. 7, 4. 9, 2. 3 Hz, 1H), 8. 02 (dd, J = 6. 6, 2. 2 Hz, 1H), 8. 56 (t, J = 2. 2 Hz, 1H), 9. 01 (d, J = 2. 2 Hz, 1H), 9. 02 (d, J = 2. 2 Hz, 1H), 10. 16 (s, 1H) ; MS (ES) : 7n/z = 251. 0 [M-H]-.
