Participants

Reaction Steps

By reaction of 4-chloroimidazo[1,2-a]quinoxaline (example 1) with isopropylamine according to a procedure that is similar to that followed in example 3 there is obtained 4-isopropylaminoimidazo[1,2-a]quinoxaline. m.p. (DSC)=102.7° C. (onset); IR (KBr): 3230, 2966, 1559 cm-1 ; 1H-NMR (DMSO-d6): δ8.55 (1H,s), 8.2÷7.95 (1H,m), 7.6÷7.4 (2H,m), 7.4÷7.2 (3H,m), 4.5 (1H,m), 1.25 (6H,d); UV (EtOH): λmax =227, 244, 285, 297, 318, 332 nm. Elementary analysis for C13H14N4 (m.w. 226.28): calcd. C 69.00, H 6.23, N 24.76%; found C 69.17, H 6.70, N 25.05%.
