7-(3,5-Dimethylisoxazol-4-yl)-6-methoxy-N4-((tetrahydro-2H-pyran-4-yl)methyl)quinoline-3,4-diamine (for preparation see intermediate 17) (50 mg, 0.131 mmol) and N-(dichloromethylene)-N-methylmethanaminium chloride (available from Aldrich) (42.5 mg, 0.261 mmol) were combined in anhydrous acetonitrile (0.5 ml) and heated at 120° C. for 10 min (microwave). The reaction mixture was reduced to dryness under a stream of nitrogen and the residue dissolved in DMSO (1 ml) and purified by MDAP (HpH). The solvent was evaporated under a stream of nitrogen to give 7-(3,5-dimethylisoxazol-4-yl)-8-methoxy-N,N-dimethyl-1-((tetrahydro-2H-pyran-4-yl)methyl)-1H-imidazo[4,5-c]quinolin-2-amine (44 mg, 0.101 mmol, 77% yield) as a yellow gum.
