Reaction Steps

To 8-nitro-3,4,5,6,11,11a-hexahydro-1H-[1,4]oxazino[4,3-b]isoquinoline hydrochloride (0.4 g) in methanol (50 ml) was added 6N hydrochloric acid (0.3 ml) and 5% Pd-C (100 mg). The mixture was treated with hydrogen at 50 psi on a Parr Hydrogenator. Hydrogen uptake was complete in 2.0 h. The catalyst was filtered off and the solvent removed under reduced pressure to yield the title product as a solid (0.4824 g).
