Methanol → methyl (1R,2S)-2-aminocyclohexanecarboxylate

Participants

Reaction Steps

cis-2-Amino-1-cyclohexane carboxylic acid (2500 mg, 17.5 mmol) was suspended in methanol (30 ml) at 0° C. Gaseous hydrochloric acid was bubbled through the suspension for 10 minutes. The reaction was allowed to reach room temperature then stirred under nitrogen for 1 h and the solvent removed under reduced pressure. The residue was azeotroped with diethyl ether (2×20 ml) and dried to give the title compound as a solid.
