This compound is prepared from 10.83 g (50 millimols) of biphenyl-4-carboxylic acid chloride and 7.94 g (62.5 millimols) of N,N-diethylacrylamide, the mixture being stirred for 50 minutes at 120° C. The crude product is extracted, in a Soxhlet extractor, with 125 ml of n-hexane, and is recrystallised once from diethyl ether. 8.5 g (15% of theory) of pale yellow crystals, melting point 113.3° C., are obtained. Analysis for C10H21NO: calculated C 81.72%, H 7.53%, N 5.02%; found C 81.44%, H 7.50%, N 4.91%.
