2-Chloro-7-(3,5-dimethyl-4-isoxazolyl)-8-(methyloxy)-1-[(1R)-1-phenylethyl]-1H-imidazo[4,5-c]quinoline (30 mg, 0.069 mmol) (for a preparation see Intermediate 12) was dissolved in NMP (0.5 ml), piperidine (0.2 ml, 2.020 mmol) was added and the mixture was heated at 150° C. for 30 min, then cooled, added to water (10 ml) and extracted with EtOAc (10 ml). The solvent was washed with water (2×10 ml), dried and evaporated. The residue was dissolved in DCM (2 ml), loaded onto a 10 g silica column, eluted with 2M methanolic ammonia/DCM (0-10%) and product-containing fractions evaporated in vacuo to give 7-(3,5-dimethyl-4-isoxazolyl)-8-(methyloxy)-1-[(1R)-1-phenylethyl]-2-(1-piperidinyl)-1H-imidazo[4,5-c]quinoline (18 mg, 0.037 mmol, 53.9% yield) as a amber solid. LCMS (formate) Rt 1.05 min, MH+ 482
