Procedure

(±)-(cis)-1-Butyryl-4-[4-(2-methyl-benzoylamino)-naphthalene-1-sulfonylamino]-piperidine-3-carboxylic acid ethyl ester was made following general procedure in Scheme 5, substituting (±)-4-amino-1-benzyl-piperidine-3-carboxylic acid ethyl ester (5) for 4-amino-piperidine-1-carboxylic acid tert-butyl ester and substituting butyl chloride for 2-isocyanato-propane. To the solution of (±)-(cis)-1-butyryl-4-[4-(2-methyl-benzoylamino)-naphthalene-1-sulfonylamino]-piperidine-3-carboxylic acid ethyl ester (70 mg, 0.12 mmol) in THF (5 mL), was added lithium hydroxide in water solution (6 mg, 0.25 mmol) and the resultant solution was stired at 25° C. for 2 h. The reaction mixture was extracted with CH2Cl2. The organic extracts were washed with brine, dried over Na2SO4, filtered and concentrated to provide the crude product. HPLC purification of the residue gave the title compound. 1H NMR (300 MHz, DMSO) δ 10.62 (s, 1H), 8.77 (t, 1H), 8.24 (m, 3H), 7.95 (d, 1H), 7.70 (m, 3H), 7.38 (m, 3H), 3.72 (m, 2H), 3.35 (m, 6H), 3.12 (m, 1H), 2.60 (m, 1H), 2.15 (m, 2H), 1.32 (m, 4H), 0.80 (dd, 3H); LC/MS m/z 539 (M+H)+
