Potassium Carbonate → HCID 21565109, compound

Participants

Reaction Steps

15.3 parts of the nitrile is dissolved in 100 parts by volume of dimethylformamide and stirred with 10 parts of potassium carbonate for 15 hours at 70°C. The whole is then diluted with 1,000 parts of water, filtered by suction and the filter residue is dried. For further purification it is sublimed at 80°C and 1 mm and the sublimate is recrystallized from methylcyclohexane. The 6-dimethylaminobenzofuran-2-carbonitrile is obtained in the form of colorless crystals having a melting point of 70° to 71°C which dissolve in benzene with an intense blue-violet fluorescence.
