Reaction Steps
15.9 g (0.05 mol) of 1-[N-(4-chloro-2-fluoro-5-methoxyphenyl)-carbamoyl]-2-hydroxymethylpiperidine (Example 1) and 4.7 g (0.06 mol) of pyridine are dissolved in 200 ml of toluene, and 6.0 g (0.05mol) of pivaloyl chloride are added dropwise at 20° C. The mixture is stirred for 3 hours at 50° C. and washed with twice 100 ml of water, and the toluene phase is dried over sodium sulfate. After the solvent as been removed, 18.4 g (92% of theory) of 1-[N-(4-chloro-2-fluoro-5-methoxyphenyl)-carbamoyl]-2-pivaloyloxymethylpiperidine are obtained in the form of a colorless viscous oil.
