To a solution of 7-(3,5-dimethyl-4-isoxazolyl)-6-(methyloxy)-N4-[1-(2-pyridinyl)ethyl]-3,4-quinolinediamine (for a preparation see Intermediate 65, 250 mg) in DCM (20 ml) was added (methyloxy)acetic acid (116 mg) followed by HATU (1.2 equiv) and triethylamine (1.5 equiv). The reaction mixture was stirred at room temperature for 1 h, and was then hydrolysed using a saturated solution of sodium hydrogen carbonate. The mixture was extracted with DCM and the organic dried over Na2SO4, filtered and concentrated to dryness. The resulting product was dissolved in ethanol (60 ml) and a solution of sodium hydroxide (1N, 15 ml) was added. The reaction mixture was heated to 90° C. for 16 h and was then allowed to cool to room temperature. DCM (150 ml) and water (100 ml) were added. The phases were separated and the organic phase was dried over Na2SO4, filtered and evaporated to dryness. The residue was purified by silica gel chromatography eluting with DCM/methanol (95:5). The resulting residue was taken-up in acetonitrile, washed with diethyl ether and dried in vacuo to give 7-(3,5-dimethyl-4-isoxazolyl)-8-(methyloxy)-2-[(methyloxy)methyl]-1-[1-(2-pyridinyl)ethyl]-1H-imidazo[4,5-c]quinoline (90 mg) as a beige powder.
