Reaction Steps

A glass Parr vessel was charged with 10% palladium on carbon (200 mg), methanol (12.5 mL), ethanol (12.5 mL) and 1-{4-amino-2-(methoxymethyl)-7-[2-(methylsulfonyl)ethenyl]-1H-imidazo[4,5-c]quinolin-1-yl}-2-methylpropan-2-ol (750 mg, 1.85 mmol). The vessel was evacuated and charged with hydrogen gas (40 psi, 2.8×105 Pa). The mixture was shaken at 50° C. for approximately 18 hours and then cooled to ambient temperature. The reaction mixture was sequentially filtered through a 0.2 micron PTFE membrane filter, concentrated under reduced pressure, and purified by chromatography using a HORIZON HPFC system (silica cartridge, eluting with 0-7% gradient of methanol in dichloromethane) to provide 195 mg of 1-{4-amino-2-(methoxymethyl)-7-[2-(methylsulfonyl)ethyl]-1H-imidazo[4,5-c]quinolin-1-yl}-2-methylpropan-2-ol as a white solid, mp 210-212° C.
