In a screw cap pressure tube, 6-tert-butyl-2-chloronicotinonitrile (410.0 mg, 2.1 mmol) was dissolved in anhydrous MeOH (3.0 ml) under N2. NaOMe (159.3 mg, 2.9 mmol) was added as a solution in anhydrous MeOH (3.0 ml). The tube was sealed and the mixture refluxed for 20 hours. The mixture was allowed to cool. NH4Cl (sat.) was added and the product extracted with EtOAc. The combined organic extracts were washed with water, dried (MgSO4), filtered and concentrated. Purification was done by flash chromatography (Pet. Ether/EtOAc 95:5) to give the title substance in 85% yield.
