Procedure

96 mg 2-{[4-bromo-1-(4-trifluoromethyl-benzyloxy)-naphthalene-2-carbonyl]-amino}-2-methyl-propionic acid methyl ester in 0.5 ml THF, 0.56 ml of 2 M sodium hydroxide and 1.4 ml methanol were reacted in a microwave at 120° C. for 6 min. The reaction was then acidified with 2 M hydrochloric acid and extracted with ethyl acetate twice. The combined organic layers were dried over magnesium sulphate, and concentrated. After purification of the residue by RP-HPLC 11 mg of 2-{[4-Bromo-1-(4-trifluoromethyl-benzyloxy)-naphthalene-2-carbonyl]-amino}-2-methyl-propionic acid were obtained.
