Procedure
Sodium azide (131 mg, 2.02 mmol) and NH4Cl (108 mg, 2.02 mmol) were added to a solution of 2-chloro-6-[4-(methylamino)piperidin-1-yl]isonicotinonitrile (Intermediate 63, 507 mg, 2.02 mmol) in anhydrous DMF (3 ml). The mixture was heated at 120° C. under nitrogen gas for 1 h where LCMS showed the expected mass. The mixture was filtered and was purified by semi-preparative HPLC eluting with acetonitrile/water (0.1% TFA) and the title compound was concentrated in vacuo to give a hygroscopic brown solid (220 mg).
