Procedure
The reaction procedure of Example 11 was followed except that 900 mg (3.21 mmol) of 2-(4-cyanoanilino)-4H-pyrido[3,2-e]-1,3-thiazin-4-one, 42 mg of lithium hydride and 655 mg of propyl iodide were used. The resulting residue was then purified through silica gel column chromatography (eluant: chloroform) to obtain 734 mg of 2-[(4-cyanophenyl)imino]-2,3-dihydro-3-propyl-4H-pyrido[3,2-e]-1,3-thiazin-4-one (71%, recrystallized from a mixture of ether and hexane) as a low polarity substance and 100 mg of 2-[N- (4-cyanophenyl)-N-propylamino]-4H-pyrido[3,2-e]-1,3-thiazin-4-one (10%, recrystallized from ether) as a high polarity substance.
