Versuchsvorschrift
The reaction procedure of Example 11 was followed except that 901 mg (3.0 mmol) of 2-(4-nitroanilino)-4H-pyrido[3,2-e]-1,3-thiazin-4-one, 30 mg of lithium hydride and 511 mg of methyl iodide were used. The resulting residue was then purified through silica gel chromatography (eluant: chloroform) to obtain 756 mg of 2,3-dihydro-3-methyl-2-[(4-nitrophenyl)imino]-4H-pyrido[3,2-e]-1,3-thiazin-4-one (80%, recrystallized from a mixture of ether and ethanol).
