실험 절차
A mixture of 4.83 g of 3-(2-amino-2-methylpropoxy)-6-chloropyridazine obtained in Example 1(a), 5.0 g of 1-[2-(2-methoxyethyl)phenoxy]-2,3-epoxypropane and 200 ml of ethanol was refluxed for 4 hours, and the solvent was evaporated under reduced pressure. A solution of the residue in benzene was extracted with 1N hydrochloric acid. The aqueous layer was extracted with chloroform, washed successively with 5% sodium carbonate and water, and the organic layer was dried over magnesium sulfate. The solvent was evaporated to give 3.8 g of 1-[2-(2-methoxyethyl)phenoxy]-3-[1,1-dimethyl-2-(3-chloro-6-pyridazinyloxy)ethylamino]-2-propanol.
