(11S)-3-(Benzyloxy)-11-isopropyl-10,11-dihydro-8H-[1,4]oxazino[4′,3′:1,2]imidazo[4,5-c]quinolin-6-amine (800 mg, 2.05 mmol) was dissolved in 260 mL of ethanol and the solution was placed in a pressure bottle. Palladium on carbon (10%, 460 mg) was then added and the reaction mixture was shaken under H2 at 48 PSI (3.3×105 Pa) overnight. The reaction mixture was filtered through a pad of CELITE filter agent. The pad was rinsed with 1:1 CH2Cl2/ethanol and the combined filtrates were concentrated under reduced pressure to give an off-white solid. Chromatography (SiO2, 20-40% CMA/CHCl3) gave the desired product (370 mg) as an off-white solid, mp 210-215° C.
