Procedure
Methyl 2-[2-(4-{2-[(4-tert-butylbenzyl)(ethyl)amino]-2-oxoethoxy}phenyl)-ethoxy]benzoate (0.2290 g, 0.455 mmol) was dissolved in a mixture of THF (freshly distilled)/water (2/1, 3 ml), lithium-hydroxide (0.218 g, 0.909 mmol) was added. The reaction was performed in a single node microwave oven (5 min, 150 deg). THF was removed by evaporation. Water was added (10 ml) and the basic water phase was washed with diethyl ether (2×10 ml). Addition of HCl (2 ml, 1 M, pH 1). The water phase was extracted with two portions of DCM (20 ml), the organic phase was dried (MgSO4) and the solvent was removed by evaporation to give 0.163 g of 2-[2-(4-{2-[(4-tert-butylbenzyl)(ethyl)amino]-2-oxoethoxy}phenyl)ethoxy]benzoic acid (yield 73.2%).
