Conditions

Temperature
85 °C

Procedure

A mixture of 4,7-dichloroquinoline (2.0 g, 10 mmol) and 1,2-diaminoethane (2.7 g, 45 mmol) is heated at 85° C. for 5 hours with magnetic stirring. After adding 1N soda (15 ml), the solid obtained is extracted with ethyl acetate (100 ml) at 50° C. The organic phase is washed with distilled water and then using a saturated NaCl solution and then again with distilled water and finally is dried on sodium sulphate. The solvent is evaporated and the product obtained is vacuum-dried (1.3 g, 58%).
