Procedure
To a solution of ethyl 2-[4-[tert-butoxycarbonyl-[2-(methanesulfonamido)ethyl]amino]cyclohexyl]acetate (0.842 g, 2.06 mmol) in methanol (4 mL); THF (4 mL) and water (4 mL) was added lithium hydroxide monohydrate (252 mg, 6 mmol). The resulting solution was stirred for 2 hours then acidified with HCl (7 mL, 1M aq.), diluted with ethyl acetate, washed with brine, dried over magnesium sulfate and concentrated. The residue was triturated with ether to give the title compound as a solid.
