A 2 L glass parr vessel was charged with of 7-(benzyloxy)-3-nitro-N-(tetrahydro-2H-pyran-4-ylmethyl)quinolin-4-amine (59.34 g, 0.151 mol), platinum on carbon (5%, 6.6 g) and acetonitrile (600 mL) to provide a black mixture. The vessel was placed on a shaker and pressurized with hydrogen gas (−50 psi, 3.4×105 Pa). After shaking for 18 hours at ambient temperature, the mixture was filtered through CELITE filter agent, and the filter cake washed with acetonitrile. The filtrate was concentrated under reduced pressure to provide 7-(benzyloxy)-N4-(tetrahydro-2H-pyran-4-ylmethyl)quinoline-3,4-diamine
