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
Part A Preparation of 5-(2,3-dihydrobenzofuranyl) sulfonyl chloride To a solution of 3.35 g of anhydrous N,N-dimethylformamide at 0 C. under nitrogen was added 6.18 g of sulfuryl chloride, whereupon a solid formed. After stirring for 15 minutes, 4.69 g of 2,3-dihydrobenzofuran was added, and the mixture heated at 100 C. for 2 hours. The reaction was cooled, poured into ice water, extracted with methylene chloride, dried over magnesium sulfate, filtered and concentrated the crude material. This was recrystallized from ethyl acetate to afford 2.45 g of 5-(2,3-dihydrobenzofuranyl)sulfonyl chloride.
The synthetic route of 496-16-2 has been constantly updated, and we look forward to future research findings.
