To a solution of 4-({(tert-butoxycarbonyl)[4-(trifluoromethyl)benzyl]amino}methyl)-benzoic acid (102 mg, 0.25 mmol), N-hydroxydodecanimidamide (70 mg, 0.33 mmol) and DMAP (3 mg, 0.03 mmol) in anhydrous DCM (15 mL) was added EDC (62 mg, 0.33 mmol) and the resulting reaction mixture was stirred at RT for 14 h. Evaporation of the solvents gave an oil. This crude product was purified by column chromatography over silica gel (AcOEt/c-Hex 80/20) to give the title compound as a colorless oil (36 mg, 24%). 1H NMR (CDCl3, 300 MHz) δ 8.01 (d, J=8.1 Hz, 2H), 7.60 (d, J=8.1 Hz, 2H), 7.40-7.20 (m, 4H), 4.88 (br s, 2H), 4.51 (s, 2H), 4.42 (s, 2H), 2.36 (t, J=8.2 Hz, 2H), 1.75-1.59 (m, 2H), 1.49 (s, 9H), 1.45-1.16 (m, 16H), 0.89 (t, J=7.0 Hz, 3H). HPLC (Condition A), Rt: 5.42 min (HPLC purity: 96.1%).
