실험 절차
0.4 g of palladium on active carbon (5% Pd) is added to a solution of 1.1 g of 2-amino-3-nitro-8-methylquinoline (compound B1) in 50 ml of methanol/tetrahydrofurane 1:1 and the resulting suspension is hydrated for 1 h. The catalyst is filtered off and the filtrate is evaporated in vacuo. The residue is chromatographed on silica gel using dichloromethane/methanol 10:1 to give 0.79 g of the title compound as colourless solid.
