Abstract
Arylamides of 8-benzylidene-2-methyl-5,6,7,8-tetrahydroquinoline-3-carboxylic acid were obtained by treating the ethyl ester with dimagnesylamines. An example is given of their conversion to 8-benzylidene-2-styryl-5,6,7,8-tetrahydroquinoline-3-carboxylic acid anilides and subsequent cyclization to 1-oxo-1,2,3,4,6,7,8,9-octa-hydrobenzo[b]-1,6-naphthyridines.
