An efficient synthesis of 1 , 3-bis ( 2-quinolyl ) propanes from aromatic aldehydes and 2-methyl quinolines using Br?nsted acid ionic liquid 1-ethyl-3-butyl imidazol p-toluenesulfonate as catalyst was described. The reaction was heated at 120℃ in toluene or solvent-free for 48 h to give the desired products in yields of 56%—92%. The structures of the products were characterized by nuclear magnetic resonance spec-trometry( NMR) and high-resolution mass spectrometry( HRMS) . The method offers several advantages inclu-ding simple work up procedure, good yields and so on.
