5 cm3 of sulfonyl chloride are added dropwise to 50 cm3 of methanol cooled to −10° C. After stirring for 10 minutes at 20° C., 5.0 g of cis-4-aminocyclohexane-1-carboxylic acid are slowly added in fractions. After stirring for 2 hours at ,20° C., the reaction mixture is concentrated to dryness under reduced pressure (2.7 kPa) at 20° C., to give 7.5 g of methyl cis-4-aminocyclohexane-1-carboxylate hydrochloride, in the form of a white powder.
