Reaction Steps

A glass Parr vessel was charged with 10% palladium on carbon catalyst (200 mg), methanol (100 mL), and 3-[4-amino-1-(2-hydroxy-2-methylpropyl)-2-(methoxymethyl)-1H-imidazo[4,5-c]quinolin-7-yl]prop-2-enenitrile (925 mg, 2.63 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. The reaction mixture was cooled to ambient temperature and then filtered through a 0.2 micron PTFE membrane filter. The filtrate was concentrated under reduced pressure and purified by chromatography using a HORIZON HPFC system (silica cartridge, eluting with a CMA:chloroform gradient; 0-25% CMA over 1500 mL, followed by 25-30% CMA over 500 mL) to provide 760 mg of 3-[4-amino-1-(2-hydroxy-2-methylpropyl)-2-(methoxymethyl)-1H-imidazo[4,5-c]quinolin-7-yl]propanenitrile as a white solid, mp 191-193° C.
