Reaction Steps

2-Amino-N-(4-tert-butyl-benzyl)-5-chloro-N-[2-(3-trifluoromethyl-phenyl)-ethyl]-benzamide (140 mg, 0.286 mmol) was dissolved in methylene chloride (2 ml). Acetic acid anhydride (32 mg, 0.315 mmol) and ethyl-diisopropylamine (41 mg, 0.315 mmol) were added and the reaction was stirred over night at RT. Further acetic acid anhydride (30 μl) was added and the reaction was stirred for another night at RT. The reaction was extracted with ethyl acetate, the combined organic layers were concentrated in vacuo and the residue was purified by flash column chromatography (heptane/ethyl acetate:7/3) to yield the desired product (110 mg, 72%) as an off-white solid. MS (ISP) 529.2 (M−H)−.
