Reaction Steps

5-(2-Methoxy-3-nitro-phenyl)-2-methyl-furan-3-carboxylic acid 53c (450 mg, 1.62 mmol) was dissolved in methanol, followed by addition of 45 mg of palladium on carbon. The reaction mixture was heated to reflux for 4 hours under hydrogen atmosphere. The reaction was monitored by TLC until the disappearance of the starting materials. The mixture was filtered and the filtrate was concentrated under reduced pressure to obtain the title compound 5-(2-methoxy-3-amino-phenyl)-2-methyl-furan-3-carboxylic acid 53d (370 mg, yield 92%) as a white solid.
