4-Formylbenzoic acid → HCID 54439766, compound

Participants

Reaction Steps

Proceeding in a manner similar to that used in Example 1, 5-methyl-2-(p-tolyl)benzofuran (2.22 g; 0.01 mole) was interacted with 2.25 g (0.01 mole) of the anil derivative of terephthalaldehydic acid in the presence of 6.72 g (0.06 mole) of potassium tert-butoxide in 150 ml of dimethylformamide. The product thus produced was sublimed to obtain 5-methyl-2-[4-(4-carboxystyryl)phenyl ]benzofuran, melting at 355°-358°C. The wavelength of maximum excitation of this compound was 374 nm and the wavelength of maximum emission was 437 nm.
