Participants

Reaction Steps

To a solution of diethyl 4-(amino)benzylphosphonate (2.02 g; 8.3 mmoles) and triethylamine (1.02 g; 9 mmoles) in toluene (7 ml) cooled to 0-5° C., is added dropwise a solution of acryloyl chloride (0.91 g of 95% purity; 10 mmoles) in toluene (2 ml) for 30 min. Thereafter, more toluene (5 ml) is poured into the flask and the mixture is stirred at room temperature for two more hours. The reaction is terminated by addition of water (10 ml). The organic phase is extracted with diethyl ether, dried over MgSO4 and stripped of solvent under vacuum to afford a pale-yellow solid (2.22 g; yield 90%).
