実験手順
The alcohol (6.97 mmol) of the preceding paragraph was dissolved in 15 mL CHCl3, followed by the addition of 0.66 mL thionyl chloride. The solution was refluxed for 1 hour and then allowed to stand at room temperature overnight. The volume was then reduced by 50% on a rotary evaporator and the solution was diluted with CCl4 and petroleum ether to induce crystallization. The product 1-(4'-chloromethylbenzoyl)piperidine was isolated in 92% yield and had a melting point of 106°-108° C.
