Procedure

To a solution of 3-chloro-5-(chloromethyl)picolinonitrile (from the previous step) in DMSO (0.2 M) was added sodium cyanide (1.25 eq). The reaction mixture was heated at 130° C. under microwave irradiation. The reaction mixture taken up in water and EtOAc, and extracted with EtOAc. Organic phases were dried over anhydrous Na2SO4, and concentrated. Flash chromatography (silica gel, 20-50% EtOAc in hexanes) of the crude afforded 3-chloro-5-(cyanomethyl)picolinonitrile.
