35700-40-4, 2,3-Dihydrobenzofuran-7-carboxylic acid is a benzofuran compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To an ice-cooled solution of 2,3-dihydrobenzo[b]furan-7-carboxylic acid (15a) (0.33 g, 2.0 mmol) in 3 ml of acetic acid there was added dropwise 0.6 ml of HNO3. The mixture was stirred in a warm oil bath (70 C.) for 24 hours, and then poured into water. After cooling, the product was collected on a filter to give 0.21 g of solid (50.2%). This was recrystallized from ethyl acetate to afford 0.14 g (33.5%) of 15k, mp 249-251.5 C.
35700-40-4, The synthetic route of 35700-40-4 has been constantly updated, and we look forward to future research findings.
