Reaction Steps
To a suspension of 10.3 g (62.37 mmol) of 5-nitro-2,3-dihydrobenzofuran in 50 mL of MeOH and 10 mL of dichloromethane was added 350 mg of 10% palladium on carbon and the mixture was placed under 55 psi of hydrogen gas. Hydrogen gas uptake was evident during the first 30 minutes. After 18 hours, the mixture was then filtered through diatomaceous earth and concentrated to afford 8.2 g of 2,3-dihydrobenzofuran-5-ylamine as a gray solid which was used without further purification.
