2-Chloro-7-(3,5-dimethyl-4-isoxazolyl)-8-(methyloxy)-1-(tetrahydro-2H-pyran-4-ylmethyl)-1H-imidazo[4,5-c]quinoline (for a preparation see Intermediate 15) (14 mg, 0.033 mmol) and ethanolamine (0.020 ml, 0.327 mmol) were dissolved in NMP (2 ml) and heated at 180° C. in the microwave for 1 h, then cooled and loaded onto a 10 g SCX-2 cartridge, washing with methanol (30 ml). The cartridge was then eluted with 2M methanolic ammonia (30 ml) and the eluant evaporated in vacuo to give a sparingly soluble brown gum. This was dissolved in DMSO (1 ml) and purified by MDAP (formate) to give 2-{[7-(3,5-dimethyl-4-isoxazolyl)-8-(methyloxy)-1-(tetrahydro-2H-pyran-4-ylmethyl)-1H-imidazo[4,5-c]quinolin-2-yl]amino}ethanol (0.80 mg, 1.772 μmol, 5.40% yield) as a pale yellow glass. LCMS (formate) Rt 0.62 min, MH+ 452
