実験手順

4M Hydrochloric acid in dioxan (40 ml, 160 mmol) was added to a solution of the more polar diastereoisomer of tert-butyl 4-hydroxy-4-methylcyclohexylcarbamate (405 g, 1.77 mmol) in dioxan (5 ml). The mixture was stirred for 3 h then the solvent was removed under reduced pressure and the residue dried in vacuo to afford a single diastereoisomer of 4-amino-1-methylcyclohexanol hydrochloride (305 mg) as a white solid.
