Aryl and heterocyclyl amide derivs. of formula (I) are new. In (I), R'=opt. substd. aryl or heterocyclyl; R2=opt. substd. alkynyl; X=O or S; E=CN, CONH2 or CSNH2. Also new are intermediates in the prepn. of (I) of formula (II) and (III). - Specifically, R'=opt. substd. phenyl, naphthyl or heterocyclyl e.g. 2-chloro-5-pyridyl, R2=3-7C opt. substd. alkynyl. |
