CN cross‐coupling of aryl chlorides with hydrazine is described. Through the use of continuousflow, the hazards associated with the use of hydrazine in the presence of transition metals are decreased. In addition, multistep flow sequences have also been developed for the generation of functionalizedheterocycles utilizing the arylhydrazine intermediates.
[Problems] To provide a compound that is useful as an agent for treating chronic renal insufficiency or an agent for treating diabetic nephropathy.
[Means for Solving Problems] The present inventors have conducted extensive studies on a compound having an EP4 receptor antagonistic action, and as a result, they have found that various amide derivatives having a carboxylic group or an equivalent thereof exhibit an excellent EP4 receptor antagonistic action, thereby completing the present invention.
Since the compound of the present invention has an excellent EP4 receptor antagonistic action, it is useful as an agent for preventing and/or treating chronic renal insufficiency or diabetic nephropathy.
