Procedure

To a solution of ethyl 2-[4-[2-(tert-butoxycarbonylamino)ethyl-methyl-amino]cyclohexyl]acetate (231 mg, 0.67 mmol) in methanol (2 mL) and THF (2 mL) was added NaOH (1 mL, 2M aqueous solution). The resulting solution was stirred for 2.75 hours then concentrated under reduced pressure to approximately ¼ the original volume. The residue was acidified with HCl (3 mL, 1M aqueous solution). This solution was purified directly by reverse phase silica chromatography (30 g of C18 silica; eluted with 5-100% acetonoitrile/water/0.1% TFA) to give the title compound.
