Reaction Steps

The reaction procedure of Example 85 was followed except that 1.576 g (10 mmol) of 2-chloronicotinic acid, 10 ml of thionyl chloride, two droplets of DMF, 837 mg of ammonium thiocyanate, 10 ml of acetone, 3.986 g of 4-acetyl-N-ethylaniline and 10 ml of acetone were used. The resulting crude product was then recrystallized from ethanol to obtain 2.729 g of 2-[N-ethyl-N-(4-acetylphenyl)amino]-4H-pyrido[3,2-e]-1,3-thiazin-4-one.
