69604-00-8, Ethyl 5-nitrobenzofuran-2-carboxylate is a benzofuran compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
20.0g of ethyl 5-nitrobenzofuran-2-carboxylate prepared in Example 2 was added into a reaction flask, 300ml of ethanol was added, 2g of 5% Pd on carbon was added, the mixture was replaced with hydrogen twice, and the hydrogen pressure was controlled to 0.3 -0.5MPa, 10-30 hydrogenation reaction for 3 hours, the reaction was completed, filtered and the filtrate was concentrated under reduced pressure to give dry 5-aminobenzofuran-2-carboxylic acid ethyl ester 17.1g, yield 98%.
The synthetic route of 69604-00-8 has been constantly updated, and we look forward to future research findings.
