Reaction Steps

To a stirring suspension of 2-(3-(4-bromopyridin-2-yl)-1-(2-fluorobenzyl)-1H-1,2,4-triazol-5-yl)thiazole (I-36, 1 equiv) in ethylene glycol-dioxane (approx. 4:1) in a sealed tube was added copper(I) cyanide (3 equiv). The resultant reaction mixture was heated at 100° C. for 24 hr and then cooled to room temperature, treated with brine and extracted with ethyl acetate. The combined organic layers were dried over sodium sulfate, concentrated and purified using SiO2 chromatography (ethyl acetate/hexanes) to afford 2-(1-(2-fluorobenzyl)-5-(thiazol-2-yl)-1H-1,2,4-triazol-3-yl)isonicotinamide as a solid in 11% yield.
