Procedure

Lithium hydroxide monohydrate (142 mg, 3.4 mmol) was added to a solution of 4-(3-{4-[(tert-butoxycarbonyl-cyclopropyl-amino)-methyl]-piperidin-1-yl}-3-oxo-propyl)-3-methyl-benzoic acid methyl ester from Example E86.1 (1.41 g, 3.1 mmol) in THF (20 ml) and water (2 ml). The mixture was stirred for 16 h at room temperature then 1M NaOH solution (5 ml) was added. The mixture was heated at 60° C. for 3 h then concentrated in vacuo. The residue was dissolved in EtOAc, washed with 1M HCl then brine, dried and concentrated in vacuo to yield the title compound (1.25 g, 91%).
