実験手順
Methyl 4-(3,4-dihydro-4-methyl-3-oxo-1,4[2H]-benzothiazin-7-yl)-4-oxo-3-methylbutyrate (1.7 g) was heated at reflux overnight with 0.3 ml of hydrazine in 50 ml of ethanol. Filtration gave a white powder which was chromatographed on silica gel eluted with 5% methanol in methylene chloride, yielding 110 mg of the named compound, mp 193°-194.5° C.
