2-(3-Methoxy-4-(4-methyl-1H-imidazol-1-yl)phenylamino)-6-((2,2,2-trifluoroethoxy)methyl)-pyrimidine-4-carbaldehyde (92 mg, 0.22 mmol) was coevaporated with dioxane and dissolved in THF (5 mL). The solution was cooled on an ice bath and (cyclopropylmethyl)magnesium bromide was added over 30 min. The mixture was quenched by addition of an ammonium chloride (aq, sat). The organic phase was separated and aquous phase was extracted with ethyl acetate (2×5 mL). The combined organic phase was dried over sodium sulfate and filtered through a short pad of silica. The solvents were removed and the residue was purified by preparative HPLC to give the title compound as a dry film 17 mg (16%).
