Reaction Steps
4-formyl-piperidine-1-carboxylic acid tert-butyl ester (1.0 eq, 13 mmol) was dissolved under inert conditions in 40 ml toluene. To this solution L-cystein ethylester hydrochloride (1.6 eq, 21 mmol) and triethylamine (1.6 eq, 21 mmol) were added. The mixture was refluxed for 14 h. The generated water was removed with a Dean & Stark trap.
