Analyzing the synthesis route of 496-16-2

As the paragraph descriping shows that 496-16-2 is playing an increasingly important role.

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

a. Preparation of 2,3-dihydrobenzo[b]furan-7-carboxylic acid (15a) To a solution of n-BuLi (1.7 M, 123 ml, 0.21 mol) in 400 ml of hexane at room temperature was added 24.3 g (0.21 mol) of N,N,N’,N’-tetramethylethylenediamine (TMEDA), followed by a hexane (40 ml) solution of 2,3-dihydrobenzo[b]furan (14) (12.56 g, 0.11 mol). The mixture was stirred under argon at room temperature for 4 hours, and then poured into dry ice (pre-washing with anhydrous ether). After stirring at ambient temperature overnight, the mixture was diluted with water (300 ml), and the layers separated. The aqueous layer was acidified with conc. HCl to pH 1, cooled and the precipitate collected on a filter. This was recrystallized from CH2Cl2 to give 15a (9.43 g, 54.7%) as a white solid, mp 167-169.5C., 496-16-2
