Reaction Steps

2-Iodoaniline (16 g, 73 mmol) was suspended in concentrated hydrochloric acid (100 mL), and then cooled to 0° C. in an ice bath. Sodium nitrite (6 g, 87.6 mmol) in water (25 mL) was added slowly to reaction mixture and then reaction allowed to stir at 0° C. for 1.5 h. In a separate flask, tin(II) chloride (84.7 g, 182.5 mmol) was dissolved in concentrated hydrochloric acid (12 mL) and added slowly over 30 min to reaction mixture. The resulting suspension was allowed to warm to rt and stirred for 14 h. The solid was filtered off, and allowed to dry to afford 1-(2-iodophenyl)hydrazine hydrochloride (19 g, 96%). 1H NMR (CDCl3, 300 MHz) δ 7.82 (dd, 1H, J=1.1, 7.7 Hz), 7.39 (dt, 1H, 1.2, 7.7 Hz), 6.96 (dd, 1H, J=1.1, 8.1 Hz), 6.82 (dt, 1H, J=1.1, 7.5) ppm. MS (ApCI) 275 (M++CH3CN+H).
