Participants

Reaction Steps

2-Chloronicotinonitrile (0.80 g, 5.8 mmol) was coupled to 2-(2-fluoro-5-nitrophenyl)-4,4,5,5-tetramethyl-[1,3,2]dioxaborolane (2 g, 7.49 mmol) using the method in Example 48. Purification by chromatography on silica gel eluting with dichloromethane gave 2-(2-fluoro-5-nitrophenyl)nicotinonitrile as a yellow solid: δH (360 MHz, CDCl3) 8.97 (1H, dd, J 5 and 2), 8.56 (1H, dd, J 6 and 3), 8.40-8.45 (1H, m), 8.15 (1H, dd, J 8 and 2), 7.55 (1H, dd, J 8 and 5), 7.43 (1H, dd, J 9 and 9); m/z (ES+) 244 (M++H).
