Participants

Reaction Steps

1-Chloroisoquinoline (J. O. C. (1958), 23, 1071) (1.64 g, 0.01 mol) and o-toluidine (1.07 g, 0.01 mol) were heated together at reflux temperature in dry dioxan (20 ml) for 18 hours. After this time a light brown oil had precipitated in the hot solution. After cooling the mixture was evaporated to dryness to give an off-white, sticky solid. This was treated with diethyl ether (50 ml), collected, washed with ether and dried to give a white solid (2.07 g). This solid was crystallised from ethanol/ ether to give the title compound (1.97 g) as its hydrochloride salt, m.p. 229°-231°.
