Procedure

To 0.198 g of 2-{[4-fluoro-1-(4-trifluoromethyl-benzyloxy)-naphthalene-2-carbonyl]-amino}-2-methyl-propionic acid methyl ester was added 15 ml of THF and 5 ml of methanol followed by 5 ml of 1 M NaOH. The solution was stirred at ambient temperature for 12 h. The reaction mixture was poured into water/ethyl acetate, acidified to pH 1-2 with 1M HCl, extracted with ethyl acetate, washed with water, dried (sodium sulphate), filtered and concentrated to a colorless oil which crystallized on standing. The material was triturated with ether, filtered and dried at 50° C. for 1.5 h to provide 45 mg of 2-{[4-fluoro-1-(4-trifluoromethyl-benzyloxy)-naphthalene-2-carbonyl]-amino}-2-methyl-propionic acid as a white solid.
