Reaction Steps

To 2-phenylbenzo[d]oxazol-5-amine (75 mg, 0.36 mmol) in dichloromethane (2 mL) at room temperature was added phenyl isocyanate (43 μL, 0.39 mmol). The solution was stirred at room temperature for 16 h. The resulting precipitate was filtered off and washed with dichloromethane to afford 99.9 mg (85%) of the title compound (LCMS RT=6.45 min, MH+ 330.1)
