Procedure

A solution of 4-(4-amino-2-fluorophenoxy)pyridine-2-amine (Compound B of Example 24, 450 mg, 2.1 mmol) in 1,2-dichloroethane (10 mL) was added slowly to a solution of acylchloride obtained above in 1,2-dichloroethane (10 mL) at ice bath temperature with stirring. The reaction mixture was allowed to stand at rt overnight. To the reaction mixture were added EtOAc (150 mL) and saturated aq. NaHCO3 solution (50 mL). The EtOAc layer was separated, dried over MgSO4 and concentrated in vacuo. The residue was purified by preparative HPLC to obtain the title compound (69 mg, 6.3%) as a yellow solid (bis-TFA salt). 1H NMR (DMSO-d6) δ 10.90 (s, 1H), 9.32 (s, 1H), 8.27 (d, 1H, J=5.5 Hz), 7.92-7.07 (m, 11H), 6.68 (dd, 1H, J=7.1, 2.2 Hz), 6.10 (d, 1H, J=2.2 Hz); MS(ESI+) m/z 217.9 (M+H)+.
