Reaction Steps

To a solution of ethyl 2-(4-chlorophenyl)-5-cyclopropyl-6-nitrobenzofuran-3-carboxylate (8 g, 18.2 mmol) in ethyl acetate (450 mL) was added 10% palladium on carbonate (1.83 g), 1N HCl solution (2.5 mL), and stirred with under 0.4 MPa of hydrogen at room temperature for 8 hrs. The reaction mixture was filtered through celite and the filtrate was evaporated under vacuum to give ethyl 6-amino-2-(4-chlorophenyl)-5-cyclopropylbenzofuran-3-carboxylate as a brown solid (7.4 g, 99%).
