実験手順
Dissolve 2-fluoro-5-(5-methoxypyridin-3-ylethynyl)-phenylamine, (prepared as described in EXAMPLE 111), (200 mg, 0.83 mmol) in pyridine (3 mL) and add acetic anhydride (84 mg, 0.83 mmol). Stir under nitrogen at room temperature for 48 h and concentrate. Purify by silica gel chromatography, eluting with 100% ethyl acetate to give the title compound as a light yellow solid (180 mg, 76%).
