5-Chlorosalicylic Acid → Imd-0354

참여 물질

반응 단계

To 30 ml of toluene were added 5-chlorosalicylic acid (862 mg, 5 mmol), 3,5-bis(trifluoromethyl)aniline (1.37 g, 6 mmol), and phosphoroustrichloride (755 mg, 5.5 mmol) in the presence of argon gas, followed by stirring for 6 hours through heat-reflux. Sodium hydrogen carbonate was added to the mixture to adjust pH to 7, followed by concentration under reduced pressure. The mixture was dissolved in 60 ml of ethylacetate, which was washed with water (40 ml×2). The organic layer was concentrated under reduced pressure, followed by column chromatography to give 1.09 g of the target compound (yield: 57%).
