Sodium Iodide → HCID 49772437, compound

Participants

Reaction Steps

To a solution of {4-[6-(3-chloro-propoxy)-3-cyano-1-cyclobutyl-1H-indol-2-yl]-phenyl}-carbamic acid isopropyl ester (37 mg, 0.08 mmol) in CH3CN (1 mL) is added sodium iodide (71 mg, 0.48 mmol). The resulting mixture is stirred at reflux temperature overnight. The solvent is then evaporated and the residue is diluted with anhydrous DMF (1 mL) and then treated with the sodium salt of 1,2,4-triazole (0.16 mmol) at room temperature overnight. The solvent is removed under reduced pressure and the residue is diluted with ethyl acetate and then washed with water. The organic layer is concentrated and triturated with hexane and the precipitate is collected by filtration and washed well with 50% ethyl acetate in hexane and dried in vacuo to afford {4-[3-cyano-1-cyclobutyl-6-(3-[1,2,4]triazol-1-yl-propoxy)-1H-indol-2-yl]-phenyl}-carbamic acid isopropyl ester, compound 1255 (31 mg, 78%).
