Procedure

The reaction mixture containing 0.27 g of 1-(6-(piperidin-4-yl)quinolin-4-yl)-3-(6-(trifluoromethyl)pyridin-2-yl)urea (0.650 mmol), 0.073 ml of 1-bromo-2-fluoroethane (0.975 mmol), 1.059 g of cesium carbonate (3.25 mmol) and 6.5 of dioxane was shaken in a flask at 60° C. for 4 h. Due to non complete reaction, additional 0.049 ml of 1-bromo-2-fluoroethane (0.650 mmol) were added and the reaction mixture was shaken at 60° C. for 18 h. Saturated sodium bicarbonate solution was added and the mixture extracted three times with ethyl acetate. The combined organic phases were washed once with brine, dried over sodiumsulfat and the solvent removed under reduced pressure. After purifying of the raw material (190 mg) by column chromatography (silica gel, DCM/MeOH 95:5) 90 mg of the desired product were obtained as beige powder (yield: 30%).
