Procedure
To a slurry of PtO2 (0.3 g) in 10 ml of ethanolwas added 2-(4-nitro-3-pyridinyl)-1,2,3,4-tetrahydroisoquinoline, N-oxide (5.0 g) in 240 ml of ethanol and this was hydrogenated with a Parr apparatus at room temperature for 24 hours. The mixture was filtered and the filtrate concentrated to yield an oil (5.1 g), which was eluted with 20% methanol/DCM on a silica gel column via HPLC. The desired fractions were concentrated to a solid (2.0 g), m.p. 216°-219° C. (decomp). This solid was recrystallized from acetonitrile to yield a solid, 1.0 g, m.p. 217°-219° C.
