Procedure

3.7 g. of 5-[{[2-[(2,6-dichlorophenyl)imino]-1-imidazolidinyl]oxy}methyl]-2,2,8-trimethyl-4H-m-dioxino[4,5-c]pyridine are dissolved in 50 ml. of ethanol, 50 ml. of 3N hydrochloric acid are added at room temperature and the mixture is left to stand for two days. The solution is evaporated and the residue is recrystallized from methanol/acetonitrile, whereupon 5-[{[2-[(2,6-dichlorophenyl)imino]-1-imidazolidinyl]oxy}methyl]-3-hydroxy-2-methyl-4-pyridinemethanol dihydrochloride, m.p. 216°-218°, is obtained.
