Versuchsvorschrift

Prepared as described for 4-hydroxy-6-(2-phenylethyl)pyridazin-3(2H)-one (Example 1) from 3,4-bis(benzyloxy)-6-[(E)-2-[3-fluoro-4-(trifluoromethyl)phenyl]ethenyl]pyridazine (Intermediate 79) in 60% yield. The solid was purified by reverse phase chromatography, eluting with 5-100% acetonitrile in water with acid modifier to yield 6-{2-[3-fluoro-4-(trifluoromethyl)phenyl]ethyl}-4-hydroxy-2,3-dihydropyridazin-3-one in 60% yield.
