Reaction Steps

Alternatively the title compound was prepared from 2-bromo-6-methyl-4-(4-trifluoromethyl-phenyl)-pyridine (example A.48) (101.0 g, 320 mmol), sodium iodide (91.04 g, 608 mmol), copper(I) iodide (2.89 g, 5 mol %) and N,N′-dimethylethylenediamine (3.31 mL, 11 mol %) in dioxane (304 mL) according to the general procedure Ia to d preparation of iodides. Obtained as a light yellow solid (112.5 g, 100%). MS (ISP) 364.0 [(M+H)+]; mp 91-93° C.
