Vorschrift

In a 100 mL round-bottomed flask (t=g) was methyl 2-bromoisonicotinate (.5 g, 2.31 mmol), 4-fluoro-N-methylaniline (0.348 g, 2.78 mmol), and CS2CO3 (1.056 g, 3.24 mmol) in toluene (16 mL) to give a yellow suspension. Pd2dba3 (0.106 g, 0.12 mmol) and biphenyl-2-yldicyclohexylphosphine (0.122 g, 0.35 mmol) were added. Reaction was allowed to stir overnight. LC/MS in the morning revealed little product had formed. Something with mass 272 dominated. Reaction was discarded.
