Procedure
Sodium hydride (obtained from 3 g of 50% suspension in mineral oil) was added to a solution of 3-bromo-7-chloro-N-(2-hydroxyethyl)-4-quinolinamine (15 g) in 30 ml of DMF and the mixture stirred at 80°-90° C. for 2 hours. After cooling, it was diluted with 300 ml of water and the product extracted with ethyl acetate. The extract was dried over sodium sulfate, the solvent was evaporated and the oily residue purified by high pressure liquid chromatography (HPLC) (hexane:ethyl acetate=1:1). The desired fractions were combined, concentrated and recrystallized from isopropanol. The yield was 2.0 g, mp 219°-220° C.
