69604-00-8,69604-00-8, Ethyl 5-nitrobenzofuran-2-carboxylate is a benzofuran compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

Commercially available ethyl 5-NITROBENZOFURAN-2-CARBOXYLATE 30 was HYDROGENATED on PD-C and ACYLATED using commercially available 4-NITRO-N-METHYL-2- TRICHLOROACETYL-PYRROLE 32 to form 33. HYDROGENATION of 33 followed by acylation with 32 afforded the nitro compound 35, which upon HYDROGENATION yielded 36 as the amino compound. ACETYLATION of the amino group of 36 followed by base catalyzed hydrolysis resulted in the acid 37. Coupling of 37 with the hydrochloride salt 39 (obtained by DEPROTECTION of the BOC derivative 38) using EDC afforded the ester 40. See Figure 4.
