Reaction Conditions:
with thionyl chloride at 80; for 4 h;
Steps:
24.24b Step 24b: Preparation of diphenyl[b,d]furan-2-carboxylate (compound 0603-96):
The compound diphenyl[b,d]furan-2-carboxylic acid (0602-96)(1.2g, 5.66 mmol, 1.0 eq)Dissolved in 50 ml of methanol,Cool in an ice bath and slowly add thionyl chloride (0.82 mL, 11.3 mmol, 2.0 equiv).Heat to 80°C and react for 4 hours.After the reaction was completed, it was concentrated under reduced pressure.Dissolve the residue in twoIn methyl chloride, saturated sodium bicarbonate solution was added and the solution was made alkaline to separate the solution. The organic phase was dried over anhydrous sodium sulfate, and spin-dry. The residue was purified by silica gel column chromatography (eluent: ethyl acetate/petroleum ether=1/5) to give the product dibenzo[b,d]furan-2-one carboxylic acidMethyl ester (650 mg, yield: 55%).
