Procedure

The reaction procedure of Example 57 was followed except that 1.595 mg (10.12 mmol) of 2-chloronicotinic acid, 15 ml of thionyl chloride, two droplets of DMF, 770 mg of ammonium thiocyanate, 15 ml of acetone, 1.35 g of 1,2,3,4-tetrahydroquinoline and 10 ml of acetone were used. As a result, 2.18 g of 2-(1,2,3,4-tetrahydroquinolin-1-yl)-4H-pyrido[3,2-e]-1,3-thiazin-4-one was obtained.
