実験手順

The reaction procedure of Example 11 was followed except that 949 mg (3.52 mmol) of 2-(4-methylanilino)-4H-pyrido[3,2-e]-1,3-thiazin-4-one, 28 mg of lithium hydride and 500 mg of methyl iodide were used. The resulting residue was then purified through silica gel column chromatography (eluant: chloroform) to obtain 698 mg of 2,3-dihydro-3-methyl-2-[(4-methylphenyl)imino]-4H-pyrido[3,2-e]-1,3-thiazin-4-one (70%, recrystallized from a mixture of ether and hexane).
