実験手順

A solution of N-({1-[4-(6-amino-pyridin-2-yl)-cyclohexyl]-azetidin-3-ylcarbamoyl}-methyl)-3-trifluoromethyl-benzamide (120 mg, 0.25 mmol) in DMF (2 mL) was treated with NaH (95%, 10 mg, 0.40 mmol) at 0° C. The reaction was stirred for 20 min. and BrCN (Aldrich, 32 mg, 0.30 mmol) was slowly added. The reaction was warmed to room temperature over 2 hours. MeOH (˜0.2 mL) was added to quenched extra NaH. The reaction solution was partitioned between DCM and water. The aqueous layer was extracted with a chloroform/IPA “cocktail” (3:1 v/v). The combined organic layers were washed with brine, dried over anhydrous Na2SO4, filtered and concentrated to give a yellow oil, which was purified by silica gel column on 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 white solid.
