Reaction Steps

Benzoyl chloride (1.41 g) was added to a solution of 4-bromopiperidine hydrobromide (2.45 g) in THF (30 ml) at 0° C., followed by triethylamine (2.2 g, 2.2 eq). The solution was stirred at room temperature for 1 h, and evaporated and. The residue was dissolved in dichloromethane (100 ml), washed with water, 1M HCl and saturated sodium bicarbonate, dried and evaporated to give the title compound as colourless oil (2.76 g, 100%).
