Versuchsvorschrift

A 1 dram vial was charged with aniline (2-3 equiv), and 0.200 mL of the 588 stock solution of bromide in toluene was added. A catalyst stock solution containing 3 mmol Pd(OAc)2, 3 mmol biphenyl-2-yl-di-tert-butyl-phosphane and 15 mL of toluene was prepared and 0.050 mL of the catalyst solution was added to the reaction. An excess of NaOtBu was added as a solid to the reaction. The vial was placed in an 80° C. oven for 60 minutes (shaken several times over the hour). After cooling, the reaction was neutralized with 0.100 mL of TPA. After 30 minutes the sample was evaporated and resolvated in 0.300 mL of DMSO. The desired compound was isolated by preparative HPLC/MS. MS(ESI) [M+H+]+=210.4.
