실험 절차

The reaction procedure of Example 57 was followed except that 824 mg (5.23 mmol) of 2-chloronicotinoyl chloride, 10 ml of thionyl chloride, two droplets off DMF, 400 mg of ammonium thiocyanate, 10 ml of acetone, 1.0 g of N-methyl-4-trifluoromethoxyaniline and 10 ml of acetone were used. The resulting crude product was then recrystallized from ethanol to obtain 1.49 g of 2-[N-methyl-N-(4-trifluoromethoxylphenyl)amino]-4H-pyrido[3,2-e]-1,3-thiazin-4-one.
