Diisopropylethylamine (0.035 mL, 0.200 mmol, 2.0 eq) was added to a solution of 4-(4-amino-2-fluorophenoxy)pyridin-2-amine (Compound B of Example 24, 0.022 g, 0.100 mmol, 1.0 eq), 2-fluoro-5-methyl benzoic acid (Aldrich, 0.015 g, 0.100 mmol, 1.0 eq), EDCI (0.021 g, 0.11 mmol, 1.1 eq) and HOBT (0.014 g, 0.100 mmol, 1.0 eq) in DMF (0.700 mL) at room temperature. The reaction mixture was stirred at room temperature for 8 h, quenched with saturated aqueous NaHCO3 solution and extracted with CHCl3 (3×10 mL). The combined organic extracts were dried (Na2SO4), filtered and concentrated in vacuo. The residue was purified by reverse phase preparative HPLC (YMC ODS-A S10 30×500 mm, 30-90% aqueous MeOH with 0.1% TFA, 30 minute gradient) and the appropriate fractions were concentrated in vacuo. The concentrate was neutralized with saturated aqueous NaHCO3 solution and the mixture extracted with CHCl3 (3×30 mL). The combined organics were dried (Na2SO4), filtered and concentrated in vacuo to afford the title compound (0.014 g, 40%) as a solid. 1H NMR (CD3OD) δ 7.67-7.80 (m, 2H), 7.36-7.45 (m, 3H), 7.03-7.14 (m, 2H), 6.14-6.16 (m, 1H), 5.89-5.90 (m, 1H), 2.29 (s, 3H); MS(ESI+) m/z 356 (M+H)+; HRMS(ESI+) calcd.: 356.1211, found: 356.1203.
