Versuchsvorschrift
To 3-Fluoro-2′-methanesulfonyl-biphenyl-4-ylamine (8.510 g) in ethyl acetate (400 ml) was added sat. NaHCO3 (100 ml) and then acryolyl chloride (1.3 equiv.). Stirred at room temperature for 3 hours. Washed EtOAc extract with brine, dried over MgSO4 and evaporated in vacuo. Triturated with ether and then filtered to afford N-(3-fluoro-2′-methanesulfonyl-biphenyl-4-yl)-acrylamide (9.670 g, 94%).
