A 5-(2-substituted-4-nitrophenyl)-oxazole is prepared by decarboxylating a 5-(2-substituted-4-nitrophenyl)-4-oxazolecarboxylic acid in an aprotic amide solvent containing a protic compound. A 5-(2-substituted-4-nitrophenyl)-oxazolecarboxylic acid and a 5-(2-substituted-4-nitrophenyl)-carboalkoxyoxazole, which are novel compounds, are provided.

5-(2-substituted-4-nitrophenyl)-oxazole подготовлено путем decarboxylating кислота 5-(2-substituted-4-nitrophenyl)-4-oxazolecarboxylic в aprotic растворителе амида содержа protic смесь. 5-(2-substituted-4-nitrophenyl)-oxazolecarboxylic кисловочное и 5-(2-substituted-4-nitrophenyl)-carboalkoxyoxazole, которые будут смесями романа, обеспечены.
