N-methyl-2-pyrrolidone → HCID 85997292, compound

Participants

Reaction Steps

Dissolving 4.4 g (24 mmol) of N-phenyl-1,2-phenylenediamine into 30 milliliter of N-methylpyrrolidone, 10 milliliter of 6-bromo picolinoyl chloride/N-methylpyrrolidone was dropped under cooling with ice. The resultant solution was further stirred at room temperature for 4 hours. After completion of the reaction, the reacted solution was poured into 400 milliliter of water and the resultant solution was further stirred. The resultant solids were separated by filtration, washed with water and methanol, dried under reduced pressure, thereby obtaining 4.5 g of 6-bromo-2′-(N-phenylamino)-picoline anilide (yield: 49%).
