Procedure

To 2-amino-4-nitrophenol (300 mg, 1.95 mmol) in dioxane (2.5 mL) was added 2-phenylacetyl chloride (290 μL, 2.15 mmol) at room temperature. The reaction vessel was heated in the microwave at 210° C. for 15 min. After cooling, the mixture was slowly poured into 1M aqueous sodium hydroxide (50 mL), and the resulting precipitate filtered and washed with water. The resulting solid was purified by column chromatography eluting using a gradient (ethyl acetate/hexanes 1:7 v/v to ethyl acetate/hexanes 1:5 v/v) to afford 165 mg (33%) of the title compound (LCMS RT=6.47 min, MH+ 255.2)
