Reaction Steps

N-Isobutyl-N-[4-(trifluoromethyl)benzyl]amine (0.172 g, 0.746 mol) was dissolved in dry acetonitrile under N2 and N-ethyl-N,N-diisopropylamine (0.371 g, 2.867 mmol) was added. The mixture was stirred for 30 min and methyl 2-{2-[4-(2-chloro-2-oxoethoxy)phenyl]ethoxy}benzoate (0.200 g, 0.573 mmol) was added. The solution was stirred over night at room temperature. The crude was purified by flash chromatography (started with isocratic heptane/EtOAc 50/50 and then the EtOAc concentration was increased to 100%, (silica gel 60 0.004-0.063 mm). The product containing fractions were pooled and the EtOAc was removed by evaporation to give 0.242 g of methyl 2-{2-[4-(2-{isobutyl[4-(trifluoromethyl)benzyl]amino}-2-oxoethoxy)phenyl]ethoxy}benzoate (yield 77.6%).
