Cesium carbonate → N-{4-[5-(2-chlorophenyl)-4-(4-{[2-(trimethylsilyl)ethoxy]methyl}-4H-1,2,4-triazol-3-yl)-1,3-oxazol-2-yl]-5-methylpyridin-2-yl}acetamide

Participants

Reaction Steps

A mixture of 3-[5-(2-chlorophenyl)-2-iodo-1,3-oxazol-4-yl]-4-{[2-(trimethylsilyl)-ethoxy]methyl}-4H-1,2,4-triazole (0.39 g, 0.78 mmol), N-[5-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2-yl]acetamide (0.36 g, 1.32 mmol), tetrakis(triphenylphosphine)palladium(0) (0.18 g, 0.16 mmol) and cesium carbonate (1.64 g, 5.04 mmol) in dioxane (13 mL) and water (1.8 mL) was subjected to microwave irradiation at 150° C. for 60 min. The reaction mixture was concentrated and the residue was purified by column chromatography to give N-{4-[5-(2-chlorophenyl)-4-(4-{[2-(trimethylsilyl)ethoxy]methyl}-4H-1,2,4-triazol-3-yl)-1,3-oxazol-2-yl]-5-methylpyridin-2-yl}acetamide (0.33 g, 81%). LCMS (AA): m/z=525.1 (M+H).
