Procedure

To 2-amino-3-methylphenol (1 g, 8.1 mmol) was added ethyl triethoxyacetate (5.4 g, 3 eq). The mixture was stirred at 110° C. overnight. The reaction mixture was cooled and triturated with hexane. Filtration gave 1.36 g of 4-methyl-benzooxazole-2-carboxylic acid ethyl ester as a white solid.
