A mixture of 3-chloro-6-(2-epoxypropoxyphenyl)pyridazine (0.7 g.), methanol (7 ml.) and t-butylamine (1.7 ml.) was stirred and heated under reflux for 1.25 hours. The mixture was evaporated under reduced pressure at 50° and the residue was recrystallized from toluene to give 3-chloro-6-[2-(3-t-butylamino-2-hydroxypropoxy)phenyl]pyridazine, m.p. 136.5°-137.5°. A sample of this product was treated with hydrochloric acid (1.0 N, 3.62 ml.), the solution was extracted with dichloromethane and the aqueous solution was evaporated under reduced pressure and the residue was recrystallized from ethanol/ether to give the monohydrochloride salt, m.p. 193.5°-194.5°.
