Participants

Reaction Steps

To a suspension of sodium hydride (60% dispersion in mineral oil; 490 mg, 12.2 mmol) in THF (10 mL) was added a solution of tert-butyl 4-hydroxypiperidine-1-carboxylate (2.46 g, 12.2 mmol) in THF (2 mL) at rt. The reaction mixture was stirred at rt for several minutes and then heated to reflux for 15 min. After cooling to rt 4-(bromomethyl)benzonitrile (2.00 g, 10.2 mmol) was added, and the reaction mixture was stirred at rt over night. Ethyl acetate was added and the mixture was washed with water. The organic layer was dried with anhydrous magnesium sulfate and filtered. The solvent was removed and the crude product was used as such for Step 2.
