実験手順

A solution of N-({1-[4-(5-iodo-2-oxo-2H-pyridin-1-yl)-cyclohexyl]-azetidin-3-ylcarbamoyl}-methyl)-3-trifluoromethyl-benzamide (as prepared in Example 8, Step C, 300 mg, 0.5 mmol), CuCN (Aldrich, 1 mmol), DMF (4 mL) in a sealed tube was irradiated under microwave at 180° C. for 30 min. The solid was filtered off and the residue was partitioned between water and a chloroform/IPA “cocktail” (˜3:1, v/v). The organic layer was dried over anhydrous Na2SO4, filtered and concentrated to give the crude product, which was then purified by a CombiFlash® system using ethyl acetate and 7N NH3 in MeOH as eluent (from pure ethyl acetate to 5% 7N NH3 in MeOH in ethyl acetate) to afford the title compound as yellow solid.
