Reaction Steps

(S)-3-Methylpiperidine-3-carboxylic acid ethyl ester (1.16 g, 6.8 mmol), benzyl chloride (0.82 ml, 7.1 mmol), K2CO3 (1.22 g, 8.8 mmol) and KI (0.056 g) were stirred and heated in DMF (50 ml) for 2.5 h. The cooled solution was poured into water and extracted with EtOAc (3×50 ml). The combined extracts were washed several times with water and finally with brine. Drying, filtering and evaporation of the solvent gave 1.64 g of the target compound as a yellowish oil.
