10% Palladium on carbon (120 mg) was added to a solution of 4-methoxy-2-nitrophenylcarbamic acid t-butyl ester (Reference Compound No. 11-1, 1.3 g, 4.8 mmol) in methanol (20 mL), and then the reaction mixture was stirred under a hydrogen atmosphere at room temperature for 9 hours. The insoluble was filtered off, and then the solvent was evaporated under reduced pressure. The resulting solid was collected by filtration with hexane to give 1.1 g of the title reference compound as a pale brown solid quantitatively.
