実験手順

A glass Parr bottle was charged with 10% palladium on carbon (0.2 g) wetted with ethanol (10 mL) and a slurry of ethyl (2E)-3-[4-amino-2-ethyl-1-(tetrahydro-2H-pyran-4-ylmethyl)-1H-imidazo[4,5-c]quinolin-7-yl]prop-2-enoate (1.81 g, 4.4 mmol) in ethanol (250 mL). The vessel was placed on a Parr apparatus, evacuated and charged with hydrogen (55 psi). The mixture was shaken at ambient temperature for 48 hours. The reaction mixture was filtered through a 0.2 micron PTFE membrane filter and the filter was rinsed with ethanol (300 ml). The filtrate was concentrated to dryness under reduced pressure. Recrystallization from acetonitrile provided 1.51 g of ethyl 3-[4-amino-2-ethyl-1-(tetrahydro-2H-pyran-4-ylmethyl)-1H-imidazo[4,5-c]quinolin-7-yl]propanoate as a white crystalline solid, mp 172-173° C.
