4M Hydrochloric acid in dioxan (40 ml, 160 mmol) was added to a solution of the more polar disatereoisomer of tert-butyl 2-hydroxy-2-methylcyclohexylcarbamate (1.52 g, 6.63 mmol) in dioxan (5 ml). The mixture was stirred for 4 h then the solvent was removed under reduced pressure and the residue dried in vacuo to afford a single diastereoisomer of 2-amino-1-methylcyclohexanol hydrochloride (1.05 g) as a white solid.
