Procedure

The title compound was prepared from the reduction of 4-(2-fluoro-4-nitrophenoxy)-3-(2-(pyridin-2-yl)ethynyl)pyridin-2-amine (35 mg, 0.10 mmol) using zinc dust (65 mg, 1.0 mmol) and NH4Cl (53 mg, 1.0 mmol) in the same manner as Step C of Example 11. This gave the title compound (25 mg, 78%) as brown oil. MS(ESI+): m/z 321.25 (M+H)+.
