実験手順

The 6:1 mixture of (4-ethylphenyl)-(3-chloro-6-methoxypyridazin-5-yl)-methanol and (4-ethylphenyl)-(3-chloro-6-methoxypyridazin-4-yl)-methanol (10.7 g), 5% palladium/carbon (5.4 g) and acetic acid (80 ml) were suspended and stirred under a hydrogen atmosphere at room temperature for 22 hours. After filtration to remove the insoluble materials, the filtrate was concentrated under reduced pressure and the resulting residue was purified by silica gel column chromatography (hexane:ethyl acetate=1:2 to chloroform:methanol=10:1) to give 4-(4-ethylbenzyl)-3-methoxy-pyridazine (2.88 g) and 4-(4-ethylbenzyl)-3-methoxy-pyridazine acetate salt (3.32 g).
