Participants

Conditions

Temperature: 90 °C

Procedure

60 mg of 2-hydroxy-benzonitrile and 70 mg of potassium carbonate were added to an N-methylpyrrolidinone (2 ml) solution of 150 mg of 5-fluoro-4-(6-methanesulfonyl-pyridin-3-yloxy)-2-nitro-phenylamine obtained in (step 3), and the reaction liquid was stirred at 90° C. for 5 hours. Water was added to the reaction liquid, and the deposit was taken out through filtration to obtain the entitled compound.
