Reaction Steps
Dissolve sodium hydride (380 mg, 9.5 mmol) in anhydrous DMF (7 mL). Cool at 0° C., add dropwise 1-hydroxy-3,3-dimethylbutan-2-one (1.1 g, 9.5 mmol) and stir at this temperature for 30 min. Add a solution of 6-bromo-nicotinonitrile in DMF (7 mL) and heat at 70° C. overnight. Cool the reaction mixture with ice/water and work-up sequentially with EtOAc and water. Dry the organic fraction over MgSO4, filter and concentrate in vacuo. Purify by chromatography on silica gel eluting with hexane/EtOAc (4:1) to obtain the desired intermediate (424 mg, 50%). MS (ES+) if/A: 219 (M+H)+.
