実験手順
In 30 ml of tetrahydrofuran was dissolved 2.6 g of 2-[4-(4-chlorobenzyl)-3,5-dichlorophenyl]-4,5-dihydro-1,2,4-triazin-3(2H)-one. To the solution was added 4.5 g of pyridinium chlorochromate. The mixture was stirred at room temperature overnight, after which the insoluble matter was filtered off. The filtrate was concentrated. The residue was purified by column chromatography (Merck Silica Gel 60; chloroform-ethanol=20:1) to provide 2.2 g of the title compound as colorless crystals, m.p. 175-176° C.
