72% | In ethanol for 18h; Reflux; | General procedure for the synthesis of 4-anilinoquin(az)olines General procedure: 4-chloroquin(az)oline derivative (1.0 eq.), aniline derivative (1.1 eq.), were suspended in ethanol (10 mL) and refluxed for 18 h. The crude mixture was purified by flash chromatography using EtOAc:hexane followed by 1-5 % methanol in EtOAc; After solvent removal under reduced pressure, the product was obtained as a free following solid or recrystallized from ethanol/water. Compounds 6-54 were synthesized as previous described32 and 60-61 as previously reported.28. |
