Reaction Conditions:
with hydrogen;palladium on activated carbon in methanol at 20; under 760.051 Torr; for 18 h;
Steps:
54.b
A solution of 226 mg (0.740 mmol) 5-nitro-3',6'-dihydro-2'H-[2,4']bipyridinyl-r- carboxylic acid tert-butyl ester (as prepared in the previous step) in 15 mL MeOH was treated with 110 mg 10 % Pd/C (Degussa type E101-NE/W, Aldrich, 50 % by weight water) and 1 atm H2 at room temperature for 18 h. The mixture was filtered through Celite, and the filter cake was washed with MeOH. Concentration afforded 220 mg (107 %) of the title compound as a colorless glassy solid. Mass spectrum (ESI, m/z): Calcd. for Ci5H23N3O2, 278.2 (M+H), found 278.0.
