496-16-2, 2,3-Dihydrobenzo[b]furan is a benzofuran compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
REFERENCE EXAMPLE 1 Synthesis of 2,3-Dihydrobenzofuran-5-carbaldehyde 2,3-Dihydrobenzofuran (100.0 g, 832.3 mmol) and N,N-dimethylformamide (133.8 g, 1830.6 mmol) were mixed and heated, and phosphorus oxychloride (255.2 g, 1643.0 mmol) was added dropwise thereto at an inner temperature of 70 to 80 C. over 2 hours. The mixture was heated to an inner temperature of 80 to 90 C., stirred for 7.5 hours, cooled and then added dropwise to 1000 g of water, followed by stirring at room temperature for 5 hours. After extracting with toluene and washing in turn with water, saturated sodium bicarbonate water and water, the organic layer was concentrated under reduced pressure to obtain a toluene solution of the title compound (yield: 340 g, apparent yield: 100%), 496-16-2
The synthetic route of 496-16-2 has been constantly updated, and we look forward to future research findings.
