Participants

Reaction Steps

1-(tert-Butoxycarbonyl)piperidin-3-ylmethanol (300 mg, 1.39 mmol) was dissolved in N,N-dimethylformamide (5 mL). While this solution was chilled in an ice bath, 60% sodium hydride in oil (83.6 mg, 2.09 mmol) was added. The reaction mixture was stirred for 10 min while ice-chilled and for another 10 min at room temperature. 2-chlorobenzothiazole (0.344 mL, 2.78 mmol) and sodium iodide (208 mg, 1.39 mmol) were then added and the mixture was stirred at room temperature for 5 hours. Subsequently, water was added and the mixture was extracted with ethyl acetate. The extract washed with brine. The washed product was then dried over magnesium sulfate and the solvent was evaporated. Purification of the resulting residue by silica gel column chromatography (hexane:ethyl acetate=20:1->5:1) gave 460 mg (95%) of the desired compound as a colorless powder.
