The invention relates to a bicyclic heteroaromatic derivative compound according to general formula (I), or a pharmaceutically acceptable salt thereof, wherein R1is NR5R6, OR5, SR5or R7; R5and R6are independently selected from H, (1-8C)alkyl, (2-8C)alkenyl, (2-8C)alkynyl, (3-8C)cycloalkyl, (2-7C)heterocycloalkyl, alkyl(1-8C)carbonyl, (6-14C)arylcarbonyl, (6-14C)aryl or (4-13C)heteroaryl, or R5and R6together are joined in a (2-7C)heterocloalkyl ring; R7is (3-8C)cycloalkyl, (2-7C)heterocycloalkyl, (6-14C)aryl or (4-13C)heteroaryl, R2is (1-8C)alkyl, (2-8C)alkenyl, (2-8C)alkynyl, or (6-14C)aryl or (4-13C)heteroaryl, both optionally substituted with one or more substituents selected from (1-8C)alkyl, (1-8C)alkylthio, (1-8C)(di)alkylamino, (1-8C)alkoxy, (2-8C)alkenyl, or (2-8C)alkynyl; R3is (1-8C)alkyl, (2-8C)alkenyl, (2-8C)alkynyl, (3-8C)cycloalkyl, (2-7C)heterocycloalkyl, or (6-14C)aryl or (4-13C)heteroaryl, both optionally substituted with one or more substituents selected from (1-8C)alkyl, (1-8C)(di)alkylamino or (1-8C)alkoxy; X is S, O or N(R4); R4is H, (1-8C)alkyl, (1-8C)alkylcarbonyl, (6-14C)arylcarbonyl or (6-14C)aryl(1-8C)alkyl; Y is CH or N; Z is NH2or OH; A is S, N(H), N(R9), O or a bond; R9can be selected from the same groups as described for R2and B is N(H), O or a bond. The compounds of the invention have LH receptor activating activity and can be used in fertility regulating therapies.

2-Aryl-3-aroyl-1,1-dicyanopropanes and 2-aryl-3-aroyl-1-bromo-1,1-dicyanopropanes were synthesized from chalcones and malononitrile and were converted into 4,6-diaryl-2-bromo-3-cyanopyridines and 3-cyano-2(1H)-pyridinethiones.The 2-aryl-3-aroyl-1-bromo-1,1-dicyanopropanes proved convenient intermediates for the production of the corresponding cyclopropanes and other compounds.By their reaction with urea a new method was developed for the production of substituted 3-cyano-2(1H)-pyridinethiones.The 2-bromo-3-cyanopyridines contain a mobile bromine atom readily exchanged for the various nucleophilic residues of alcohols and amines and for iodide, and cyano and thiocyanato groups.The 3-cyano-2(1H)-pyridinethiones were used in the synthesis of 3-aminothienopyridines through the isolated 2-Z-methylthio-3-cyanopyridines.
