A mixture of 6-chloro-biphenyl-3,4′-dicarboxylic acid 4′-ethyl ester (800 mg), N-(4-aminophenyl)morpholine (469 mg), EDAC (504 mg), HOBT (355 mg) and N-methylmorpholine (578 μl) in DMF (10 ml) was stirred at room temperature. After 1 h, water (80 ml) was added and the resulting suspension filtered. The residue was then purified by chromatography. Elution with 1:1 ethyl acetate:petrol gave a yellow crystalline solid (437 mg).
