To a solution of 53 mg of 2-amino-5-chloro-benzoic acid (0.33 mmol) and 105 mg (0.33 mmol) of (4-cyclopropyl-benzyl)-[2-(3-trifluoromethyl-phenyl)-ethyl]-amine in 4.5 ml of DMF were added 171 mg of HBTU (0.45 mmol) and 0.1 ml (0.9 mmol) of 4-methyl-morpholine. After stirring the reaction mixture over night at RT it was diluted with 50 ml water and extracted with ethyl acetate. The combined organic phases were washed with 10% aqueous KHCO3 solution, 0.1M HCl solution and brine, dried with magnesium sulfate, filtered and concentrated in vacuo. The remaining oil was purified by column chromatography (silica gel; heptane/EtOAc 6:1) to give 127 mg (88%) of 2-amino-5-chloro-N-(4-cyclopropyl-benzyl)-N-[2-(3-trifluoromethyl-phenyl)-ethyl]-benzamide as a yellow oil. MS (ISP) 473 (M+H)+.
