Reaktionsschritte
A stirred mixture of 5-(4-aminophenyl)-6-methyl-3H,6H -1,3,4-thiadiazine-2-one (0.54 g). 4H-pyran-4-one (0.26 g), glacial acetic acid (0.15 g) and water (20 ml) was heated under reflux for 24 hours to give a solid. 0.54 g. Recrystallisation from aqueous ethanol gave the title compound, 0.28 g, which darkened at 265° C. and sublimed at 273-275° C.
