실험 절차
Ten grams of 4-amino-3,5-dichloro-2-(2-hydroxyethoxy)pyridine, prepared in Example I, was dissolved in 50 milliliters of 5 Normal hydrochloric acid, at ambient temperature, with agitation. The solid which precipitated was recovered by filtration under reduced pressure and dried. The 4-amino-3,5-dichloro-2-(2-hydroxyethoxy)pyridine, hydrochloride product was recovered in a yield of 95 percent of theoretical and melted at 169° C. to 170° C.
