Reactions of N-Alkyl-N-phenyl-1H-benzotriazole-1-methanamines with α,β-Unsaturated Ethers. A Novel Route to 1,4- and 1,3-Disubstituted 1,2,3,4-Tetrahydroquinolines

N-Alkyl-N-aryl-1H-benzotriazole-1-methanamines 3, easily accessible from the condensation of anilines with formaldehyde and benzotriazole, undergo acid-catalyzed reactions with ethyl vinyl ether to give 1-alkyl-4-(benzotriazol-1-yl)-1,2,3,4-tetrahydroquin
