Using a method similar to the procedure described for the preparation of 4-[4-(2-nitro-phenyl)-oxazol-2-yl]-butyric acid methyl ester; reaction of 2-bromo-2′-nitroacetophenone (8.9 g, 36.5 mmol) with 6-carbamoyl-hexanoic acid ethyl ester (9.1 g, 48.7 mmol) gives 6-[4-(2-nitro-phenyl)-oxazol-2-yl]-hexanoic acid ethyl ester (3.19 g, 26%). MS (ES): (M+1)+ 333.2, 334.4 m/z.
