and X are defined as in the claims, the tautomers, the enantiomers, the diastereomers, the mixtures thereof and the salts thereof, and processes for preparing them and their use as intermediates for preparing pharmaceutical compositions or pesticides.
Synthesis of 2-bromo-7-methyl-3,5-dihydro-imidazo[4,5-d]pyridazin-4-one and 3-alkyl-2-bromo-3,5-dihydro-imidazo[4,5-d]pyridazin-4-one and their selective elaboration
Two synthetic routes to the versatile 3,5-dihydro-imidazo[4,5-d]pyridazin-4-ones 2 and 5 have been developed that allow the production of multigram quantities without the need of any chromatographic purification. Broad and selective elaboration of the heteroaromatic scaffolds has also been accomplished. (c) 2008 Elsevier Ltd. All rights reserved.
