Procedure

When 5-chloro-2-(p-tolyl)benzofuran was condensed with the anil derivative of terephthalaldehydic acid according to the procedure described in Example 1, there was obtained 5-chloro-2-[4-(4-carboxystyryl)phenyl]benzofuran which melted at 347°-348°C following recrystallization from trichlorobenzene. The wavelength of maximum excitation of this compound was 372 nm and the wavelength of maximum emission was 424 nm.
