Procedure

A sample of 2-{4-[2-(2-biphenyl-4-yl-5-methyl-thiazol-4-yl)-ethoxy]-phenoxy}-2-methyl-propionic acid ethyl ester (400 mg, 0.8 mmol) was dissolved in EtOH (15 mL) and 5N NaOH (5 mL) added. The reaction was warmed at 40° C. for 1.5 h and then cooled to room temperature. After removing some of the EtOH, the reaction was acidified with HCl. After stirring in an ice-bath for 1 h, the yellow solid was collected and dried to give 328 mg (87%) acid as a yellow powder, mp 174° C., MS (m/e) 474 (MH); 1H NMR (CDCl3) δ 1.53 (s, 6H), 2.57 (s, 3H), 3.48 (t, 2H), 4.44 (t, 2H), 6.80 (d, 2H), 6.91 (d, 2H), 7.40-7.54 (m, 3H), 7.51 (d, 2H), 7.64 (d, 2H), 8.26 (d, 2H).
