Procedure

A mixture of 2-(2-fluoro-5-{2-methoxy-6-[2-(4-trifluoromethoxy-phenyl)-ethylamino]-pyrimidin-4-yl}-phenyl)-2-methyl-propionic acid methyl ester (should this be the right starting material? 1.9 g) and sodium hydroxide (2.46 g) in water (19 mL), MeOH (19 mL) and THF (19 mL) is stirred at 40° C. for 40 hours. The solution is evaporated in vacuo and acidified to pH=6 with concentrated HCl (1.6 mL). The solid is filtered, air dried and chromatographed on silica gel eluting with 50% EtOAc in heptane to afford 2-(2-fluoro-5-{2-methoxy-6-[2-(4-trifluoromethoxy-phenyl)-ethylamino]-pyrimidin-4-yl}-phenyl)-2-methyl-propionic acid (1.12 g, Example 70). MS: 494 (M+H); 1H NMR (300 MHz, CD3OD) 07.8, (d, 1H, J=0.3 Hz); 7.7 (m, 1H); 7.4 (d, 2H, J=0.4 Hz); 7.2-7.3 (m, 4H); 6.6 (s, 1H); 4.2 (s, 3H); 3.9 (m, 2H); 3.05 (t, 2H); 1.65 (s, 6H). IC50=193 mM
