Reaction Steps

The reaction procedure of Example 85 was followed except that 2.347 g (15.1 mmol) of 2-chloronicotinic acid, 30 ml of thionyl chloride, three droplets of DMF, 1.262 g of ammonium thiocyanate, 15 ml of acetone, 2.583 g of N-ethyl-4-isopropylaniline and 10 ml of acetone were used. The resulting crude product was then recrystallized from a mixture of ethanol, ether and hexane to obtain 3.388 g of 2-[N-ethyl-N-(4-isopropylphenyl)amino]-4H-pyrido[3,2-e]-1,3-thiazin-4-one.
