Reaction Steps

Analogously to Example 14, 1.39 g (5 mmol) of 2-chloro-6-[1-methyl-3-(trifluoromethyl)-pyrazol-5-yloxy]pyridine, 0.75 g (7.57 mmol, 98 percent content) of 2,2,2-trifluoroethylamine, 0.80 g (7.55 mmol) of anhydrous sodium carbonate, 5.6 mg (25 μmol) of palladium(II) acetate and 88 mg (0.25 mmol) of tris(4-methoxyphenyl)phosphine in 20 ml of methylcyclohexane were reacted under a CO pressure of 21 bar. The yield was 0.96 g (75.4 percent) of a white solid. The melting point was 135.8° to 136.3° C. (from methylcyclohexane). Other data concerning the product was:
