Reaktionsschritte

The reaction procedure of Example 57 was followed except that 1.203 g (7.63 mmol) of 2-chloronicotinic acid, 15 ml of thionyl chloride, two droplets of DMF, 639 mg of ammonium thiocyanate, 15 ml of acetone, 1.53 g of N-ethyl-4-bromoaniline and 10 ml of acetone were used. The product was then recrystallized from ethanol to obtain 2.08 g of 2-[N-(4-bromophenyl)-N-ethylamino)-4H-pyrido[3,2-e]-1,3-thiazin-4-one.
