Reaction Steps
Add iso-propanol (2.2 g, 25 mmol) and tetrabutylammonium sulfate (28 mg, 0.08 mmol) to a solution of potassium hydroxide (7.1 g, 127 mmol) in water (7 mL) and stir at room temperature for 15 min. Add 6-bromomethyl-pyridine-3-carbonitrile (1 g, 5.08 mmol) and stir the mixture for 24 h at room temperature. Add water (15 mL) and extract with DCM (15 mL). Filter through an IST® phase separator frit to separate the organic phase and concentrate in vacuo. Purify by chromatography on silica gel eluting with hexane/EtOAc (1:0 to 1:1 gradient) to obtain the desired intermediate as a crystalline solid (0.4 g, 45%). MS (ES+) m/z: 177 (M+H)+.
