Lithium Hydroxide → 2-[(4-{3-[Butyl(2,3-dimethoxybenzyl)amino]-3-oxopropyl}phenoxy)methyl]benzoic acid

Participants

Reaction Steps

Methyl 2-[(4-{3-[butyl(2,3-dimethoxybenzyl)amino]-3-oxopropyl}phenoxy)methyl]-benzoate (15 mg, 0.029 mmol) was dissolved in THF/water (2/1, 2 ml) and LiOH (1.4 mg, 0.058 mmol) was added. The reaction was performed in a single node microwave oven (150° C., 7 min). Workup was done by adding EtOAc (10 ml) and washing the organic phase with two portions of HCl (2×5 ml, 1 M). The organic phase was dried (MgSO4) and the solvent was removed by evaporation to give 13 mg of 2-[(4-{3-[butyl(2,3-dimethoxybenzyl)amino]-3-oxopropyl}phenoxy)methyl]benzoic acid (yield 89%).
