Procedure

To a solution of N2-[(1S)-1-(4-bromophenyl)-2,2,3,3,3-pentafluoropropyl]-N1-(cyanomethyl)-L-leucinamide (82 mg, 0.18 mmol), 4-pyridylboronic acid (30 mg, 0.24 mmol) and PdCl2(dppf) (14 mg, 0.02 mmol) in 2.5 mL DMF was added 2M Na2CO3 (0.25 mL). The mixture was heated to 95° C. for 2.5 h, then cooled and partitioned between aq. Na2CO3 and ether. The aqueous phase was washed with brine and dried over MgSO4. Purification by silica gel chromatography (65% to 95% ethyl acetate/hexanes gradient) provided the title compound.
