To a solution of 4-(5-chlorobenzo[d]oxazol-2-yl)aniline (122.3 mg, 0.50 mmol) in pyridine (3 mL) at room temperature was added acetyl chloride (39 μL, 0.55 mmol). The resulting mixture was stirred at room temperature for 16 h. The solution was then poured into water, and the resulting precipitate collected by filtration. The solid was washed with diluted hydrochloric acid solution, followed by diluted sodium hydroxide solution, and then by water to afford 120 mg (84%) of the title compound (LCMS RT=6.38 min, MH+ 287.0)
