A Microwave Assisted Diazo Coupling Reaction: The Synthesis of Alkylazines and Thienopyridazines
摘要:
Heating diazoaminobenzene with active methylene compounds 1-3 in microwave oven in acetic acid, in the presence of hydrochloric acid, afforded the corresponding arylhydrazones 5-7. These reaction products were condensed with ethyl cyanoacetate in a domestic microwave oven after 1-2 minutes heating to yield the pyridazinones 8-12. Compounds 8c and 12 reacted with sulfur in basic DMF solution, in microwave oven using MORE technology to yield the thienopyridazinone 14 and 16 respectively. While 17 was produced when 8b was treated like wise with sulfur and DMF in the presence of piperidine. Compounds 16 coupled with aromatic diazonium salts to yield arylazo derivatives 21a-c.

The present invention relates to compounds useful as CCR9 modulators, to compositions containing them, to methods of making them, and to methods of using them. In particular, the present invention relates to compounds capable of modulating the function of the CCR9 receptor by acting as partial agonists, antagonists or inverse agonists. Such compounds may be useful to treat, prevent or ameliorate a disease or condition associated with CCR9 activation, including inflammatory and immune disorder diseases or conditions such as inflammatory bowel diseases (IBD).
