The procedure described in Example 1 was repeated (using the same molar proportions as before) except that 440 mg. (0.002 mole) of 2-oxo-1-benzimidazolineacetic acid ethyl ester and 353 mg. (0.002 mole) of 2-chloromethylnaphthalene were reacted to afford 583 mg. (81%) of 3-(β-naphthyl)methyl-2-oxo-1-benzimidazolineacetic acid ethyl ester, isolated as an oil.
