実験手順

Analogously to Example 3, 6.84 g (25 mmol) of 3-chloro-2-(3-trifluoromethyl)phenoxypyridine (prepared according to Example 2), 4.84 g (37.5 mmol) of 2,4-difluoroaniline, 2.92 g (27.5 mmol) of sodium carbonate, 17.5 mg (25 μmol) of dichlorobis(triphenylphosphine)palladium(lI) and 0.31 g (0.75 mmol) of (±)-1-[2-(diphenylphosphino)ferrocenyl]ethyl-di-tert-butylphosphine in 25 ml of xylene were reacted under a CO pressure of 15 bar at 150° C. for 19 hours. The conversion was ca. 70 percent. The mixture was worked up as in Example 3 to give 6 g of crude product in the form of a yellow crystalline solid. It was purified by recrystallization from 50 ml of methylcyclohexane. The yield of the title compound was 3.25 g (33 percent) of a white solid. Other data concerning the title compound was:
