Reaction Steps
3-Iodo-4-methylphenyl amine (10 g, 43 mmol) was dissolved in 6 N HCl (40 mL), cooled to 0° C., and vigorously stirred throughout the procedure. Sodium nitrite (2.9 g, 1.03 equiv.) was dissolved in water (5 mL) and this solution was added to the reaction in a dropwise fashion. After 30 min, tin (II) chloride dihydrate (22.8 g, 1 mol) in 6 N HCl (100 mL) was added via addition funnel, and the reaction slurry was stirred at 0° C. for 3 h. The pH was adjusted to 14 with 40% aqueous sodium hydroxide solution and the aqueous mixture was extracted with EtOAc, (6×50 mL), dried (MgSO4), and concentrated to give 3-iodo-4-methylphenylhydrazine (7 g, 57%). This material was used directly without further purification.
