Reaction Steps

By reaction of 4-chloroimidazo[1,2-a]quinoxaline (example 1) with piperidine, according to a procedure that is similar to that followed in example 3, there is obtained 4-(1-piperidinyl)imidazo[1,2-a]quinoxaline. m.p. (DSC)=108.2° C.(onset); IR (KBr): 3107, 2935, 1517 cm-1 ; 1H NMR (CDCl3): δ7.9 (1H,d, J=2 Hz), 7.75÷7.4 (3H,m), 7.4÷7.1 (2H,m), 4.3 (4H,t), 1.9÷1.6 (6H,m), 7.75÷7.4 (3H,m), 7.4÷7.1 (2H,m), 4.3 (4H,t) 1.9÷1.6 (6H,m); UV (EtOH): λmax =231, 249, 293, 305, 333 nm. Elementary analysis for C15H16N4 (m.w.252.32): calcd. C 71.40, H 6.39, N 22.20%; found C 71.38, H 6.63, N 22.61%.
