Reaction Steps

To a 250mL 3 neck round bottom flask equipped with a mechanical stirrer, thermometer, addition funnel, and nitrogen inlet, were charged 98.1 mL of tetrahydrofuran, 3.27 grams (9.83 mmoles) of the 2-chloro-3-(2-methoxy-5trifluoromethoxybenzylamino) pyridine and 1.93 grams (2.95 mmoles) of bis(triphenylphosphino)nickel(II) chloride. The black reaction mixture was stirred at 25 degree celsius for 40 minutes. Phenylmagnesium bromide (1M/THF, 38.4 mL, 38.4 mmoles) was added over a 25 minute period and the resulting black slurry was stirred for 2 hours at 25 degree celsius. During this time, the reaction was monitored by thin layer chromatography assay. The reaction mixture was cooled to 4° C., and quenched with 5.89 mL acetic acid. The reaction mixture was vacuum concentrated to a low volume and partitioned between 100 mL each of toluene and water. The organic layer was washed several times with water and concentrated to an oil. The oil was purifid by column chromatography to yield 1.88 grams (51.1%) of the desired material (as an oil). The structure of this compound was assigned on the basis of high resolution NMR. 1H NMR (CDCl3) 8.05 (d, 1H), 7.63 (d, 2H), 7.45 (m, 3H), 7.12 (bs, 1H), 7.08 (m, 2H), 6.93 (dd, 1H), 6.85 (d, 1H), 4.71 (t, 1H), 4.26 (d, 2H), 3.78 (s, 3H).
