Participants

Reaction Steps

To a mixture of (2E)-3-(2-furyl)acrylic acid (660 g, 4.78 mol) and triethylamine (800 mL, 5.74 mol) in tetrahydrofuran (960 mL) was added diphenylphosphoryl azide (1.13 L, 5.26 mol) under ice-cooling. After stirring at room temperature for 4 hr, the reaction solution was poured into a mixture of ethyl acetate and saturated aqueous sodium hydrogen carbonate solution, and the mixture was extracted with ethyl acetate. The extract was dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The residue was washed with methanol to give the title compound (580 g, yield 74%).
