YieldReaction ConditionsOperation in experiment
99% With sulfuric acid; at 80℃; for 17h; INTERMEDIATE 65 Methyl 2, 3-dihydro-1-benzofuran-7-carboxylate 2, 3-Dihydrobenzofuran-7-carboxylic acid (8 g, 48. 7 mmol) was dissolved in methanol (39.6 mL, 975 mmol) and concentrated sulfuric acid (2.6 mL, 48. 7 mmol) was slowly added. The mixture was refluxed at 80 C for 17 h. The solvent was evaporated and the residue was dissolved in ethyl acetate and washed with brine. The organic layer was evaporated to give the title compound as a beige solid. Yield: 8.6 g (99%). HPLC purity 93%, RT=1.72 min (System A; 10-97% MeCN over 3 min); 96%, RT=1.67 min (System B; 10-97% MeCN over 3 min). MS (ESI+) for CloHlo03 m/z 179 (M+H) +.
