Procedure

4-(4-Carboxy-naphthalene-1-sulfonylamino)-piperidine-1-carboxylic acid tert-butyl ester 5 (400 mg, 0.92 mmol) was dissolved in dichloromethane (5 mL). 1-[3-(Dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (EDCI) (350 mg, 1.84 mmol), 1-hydroxybenzotriazole (186 mg, 1.38 mmol), triethylamine (280 mg, 0.38 mL, 2.76 mmol) and cyclohexylamine (0.14 g, 0.16 mL, 1.38 mmol) were added and the reaction was stirred overnight at room temperature. The reaction was diluted with dichloromethane (30 mL) and charged to a separatory funnel. The organic layer was washed twice with water and brine and dried over Na2SO4. Filtration and concentration in vacuo afforded a foam that was purified via flash column chromatography (98:2 dichloromethane:methanol) to give the title compound. Wt.: 320 mg (68%). 1H NMR (300 MHz, CDCl3) δ 8.61 (m, 1H), 8.31 (m, 1H), 8.26 (d, 1H), 7.68 (m, 2H), 7.59 (d, 1H), 5.91 (d, 1H), 4.64 (d, 1H), 4.12 (m, 1H), 3.82 (m, 2H), 3.22 (m, 1H), 2.68 (m, 2H), 2.13 (m, 2H), 1.79 (m, 2H), 1.57 (m, 6H), 1.38 (s, 9H), 1.27 (m, 4H); LC/MS m/z 516 (M+H)+.
