Participants

Reaction Steps

To a slurry of 3-(3-acetamido-4-methylphenyl)propenoic acid (20.11 g, 91.7 mmol) in acetone (450 mL) at 0° C. is added triethylamine (12.8 mL, 91.8 mmol) followed by dropwise addition of ethyl chloroformate (11.8 mL, 123 mmol) over a 10 minutes period. The resulting yellow slurry is stirred using a mechanical stirrer for 1.5 hours, then a solution of sodium azide (8.94 g, 138 mmol) in water (25 mL) is added slowly so as to maintain the temperature below 5° C. The thick mixture is stirred at 0° C. for 1 hours, then the ice bath is removed and the reaction mixture allowed to warm to room temperature. The suspension is poured over water (800 mL) then filtered. The remaining solid is washed generously with water and dried under vacuum over P2O5 overnight to give the product as a pale yellow solid (21.40 g, 87.6 mmol).
