Reaction Steps

In a small autoclave, 1.5 g (2.73 mmoles) of 4-[2-(3,5-Bis-trifluoromethyl-benzyloxy)-1-(4-carboxymethyl-piperazin-1-yl)-ethyl]-benzoic acid methyl ester (compound 318) were dissolved in methanol. The solution was saturated with NH3 and heated at 100° C. for three days. Methanol was then evaporated and the crude product was purified by chromatography (eluent: CH2Cl2/MeOH/NH3: 80/20/0.5 v/v/v) to give 880 mg of {4-[2-(3,5-Bis-trifluoromethyl-benzyloxy)-1-(4-carbamoyl-phenyl)-ethyl]-piperazin-1-yl}-acetic acid (compound 321) as a grey solid. 4-[2-(3,5-Bis-trifluoromethyl-benzyloxy)-1-(4-carbamoylmethyl-piperazin-1-yl)-ethyl]-benzamide (compound 322) was isolated as a side product (150 mg).
