3-(2-Ethoxycarbonylethenyl)-2-methyl-7-nitrobenzo[b]furan → 7-Amino-3-(2-ethoxycarbonylethyl)-2-methylbenzo[b]furan

Participants

Reaction Steps

10%-Palladium on carbon (30 mg) was added to a solution of 3-(2-ethoxycarbonylethenyl)-2-methyl-7-nitrobenzo[b]furan (210 mg) in a mixture of dioxane (3 ml) and ethanol (1 ml). The mixture was hydrogenated at 3 atoms for 3 hours and the catalyst was filtered off. The filtrate was concentrated in vacuo to give 7-amino-3-(2-ethoxycarbonylethyl)-2-methylbenzo[b]furan (195 mg).
