Reaction Steps

A mixture of 8.0 g of 3-bromo-N-(2-hydroxyethyl)-4-quinolinamine and 4 g of potassium-tert-butoxide in 220 ml of dimethylformamide was heated at reflux for 3 hours. The reaction mixture was cooled to room temperature and diluted with 200 ml of water and the product was extracted with 4 portions of 50 ml of dichloromethane (DCM). The DCM solution was dried over sodium sulfate and concentrated. The oily residue was dissolved in 150 ml of ethanol. To this solution 5 ml of concentrated HCl was added, the HCl salt was separated by filtration and recrystallized from ethanol. This crystalline material was dissolved in 75 ml of water and the solution made alkaline (pH=8) with a sodium bicarbonate solution. The free base was filtered and dried in vacuo to yield 1.3 g of white solid, mp 175°-176° C.
