Procedure
2-Amino-5-(3', 4'-dichlorobenzoyl)oxazole (2 g, 7.8 mmol) was combined with aqueous dimethylamine (100 ml) in t-butyl alcohol and stirred at room temperature for 4 hours. The solvents were removed in vacuum and the residue was chromatographed on silica gel with hexane and ethylacetate (3:1) as the eluent to yield 1.5 g of the title compound as a crystalline solid, m.p. 188°-189° C.
