Versuchsvorschrift
Tin(II) chloride (11.87 g, 62.6 mmol) and 3-(2-chloro-5-nitrophenyl)pyridine (3.53 g, 15.1 mmol) were reacted as described in Example 62 to give 4-chloro-3-(pyridin-3-yl)phenylamine (2.69 g, 87%) which was used without purification on silica: δH (360 MHz, CDCl3) 6.65-6.70 (2H, m), 7.26 (1H, dt, J 8.5 and 1.1), 7.33 (1H, dd, J 7.8 and 4.8), 7.77 (1H, dt, J 7.8 and 1.9), 8.59 (1H, dd, J 4.8 and 1.6), 8.66 (1H, d, J 1.8); m/z (ES+) 205, 207 (3:1) (M++H).
