4-functionally substituted 3-heterylpyrazoles: XVIII. Intramolecular cyclization of N-[3-(2-Chlorophenyl)-4-pyrazolyl]methylamine and its N-alkyl derivatives into 4,5-dihydro-2H-pyrazolo[4,3-c]quinolines
摘要:
N-[3-(2-Chlorophenyl)-4-pyrazolyl]methylamine and its N-alkyl-derivatives at heating in DMF in the presence of K2CO3 undergo an intramolecular cyclocondensation yielding 4,5-dihydro-2H-pyrazolo[ 4,3-c]quinolines.
