Reaction Steps

A glass Parr vessel was charged with 10% palladium on carbon (0.05 g), methanol (20 mL), and 3-[4-amino-2-ethyl-1-(tetrahydro-2H-pyran-4-ylmethyl)-1H-imidazo[4,5-c]quinolin-7-yl]prop-2-enenitrile (100 mg, 0.27 mmol). The vessel was evacuated and charged with hydrogen gas (40 psi, 2.8×105 Pa). The reaction was shaken at 50° C. for approximately 18 hours and then cooled to ambient temperature. The reaction mixture was sequentially filtered, concentrated under reduced pressure, and purified by chromatography using a HORIZON HPFC system (silica cartridge, eluting with a CMA:chloroform gradient, 0-30% CMA). A final recrystallization from acetonitrile provided 71 mg of 3-[4-amino-2-ethyl-1-(tetrahydro-2H-pyran-4-ylmethyl)-1H-imidazo[4,5-c]quinolin-7-yl]propanenitrile as a white solid, mp 273-275° C.
