Versuchsvorschrift

To a solution of trans-4-aminocyclohexane carboxylic acid hydrochloride (5.0 g, 34.92 mmol) in aqueous 2.0N NaOH (35 mL) is added benzyl chloroformate (5.0 mL, 34.92 mmol). The mixture stirs for 1.5 h. Then the suspension is acidified with 12N HCl (aq) to pH=1. H2O is added (100 mL) and the precipitate is filtered off. The filter cake is dried to afford 8.2 g of 4-benzyloxycarbonylamino-cyclohexanecarboxylic acid. LC/MS: [M+H]+=278, Rt=0.85 min (method 6)
