A mixture of 2-(benzyloxycarbonylamino)-3-(1-methylcyclohexyl)propyl methanesulfonate in 16 mL of THF, and 10 mL of 33% wt. methylamine in EtOH was heated at 70° C. for 3 h. After cooling to rt, the reaction mixture was evaporated under reduced pressure. The crude benzyl 1-(methylamino)-3-(1-methylcyclohexyl)propan-2-ylcarbamate was used directly in the next step without further purification. MS ESI +ve m/z 319 (M+H).
