Procedure

Thionyl chloride (2.86 mL, 39.2 mmol) was added to a chilled (0° C.) solution of 3-[(2,3-dimethyl-5-nitro-6-phenoxypyridin-4-yl)amino]propan-1-ol (11.3 g, 35.6 mmol) in dichloromethane (170 mL). The reaction mixture was stirred at ambient temperature for 0.5 hr and then heated at reflux for 0.5 hr. The reaction mixture was allowed to cool to ambient temperature. A precipitate was isolated by filtration and then dried under vacuum to provide 13.64 g of N-(3-chloropropyl)-2,3-dimethyl-5-nitro-6-phenoxypyridin-4-amine hydrochloride.
