Reaction Steps

A stirred solution of 1-Bromo-1-(3-nitro-phenyl)-propan-2-one (98a) (2.4 g, 9.3 mmol) in ethanol (20 ml) at room temperature is treated with thiourea (0.71 g, 9.3 mmol). The reaction mixture is heated to 70° C. for 10 minutes. The resulting precipitate is removed by filtration and dried under vacuum to give the titled compound.
