With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.174543-74-9,Methyl N-Cbz-3-piperidinecarboxylate,as a common compound, the synthetic route is as follows.
To a solution of 1-benzyl 3-methyl piperidine-1,3-dicarboxylate (2.0 g, 7.14 mmol) in THF (60 mL) was added LDA (2.0 M in THF) (10.8 mL, 21.66 mmol) dropwise at -78 C. After the solution was stirred for 30 mm at -78 C, S-(trifluoromethyl)dibenzothiophenium trifluoromethanesulfonate (4.35 g, 10.81 mmol) was added. After addition, the resulting solution was allowed to react, with stirring, for an additional 2 h at -40 C. The reaction was then quenched by the addition of 30 mL of a saturated aqueous solution of NH4C1. The resulting mixture was extracted with EtOAc (3 x 70 mL). The combined organic layers were dried over anhydrous sodium sulfate, filtered, and concentrated under vacuum. Purification by silica gel chromatography (eluting with 1:4 EtOAc/pet. ether) afforded 1-benzyl 3-methyl 3-(trifluoromethyl)piperidine-1,3- dicarboxylate as a yellow oil. MS: (ESI, m/z): 346 [M+H].
