PYRROLOPYRIDINE DERIVATIVE AND USE THEREOF
-
Page/Page column 45, (2008/06/13)
A novel pyrrolopyridine derivative which is a compound represented by the formula ???wherein Ring A represents an optionally substituted pyridine ring; X represents an electron-attracting group; Y represents an optionally substituted divalent C1-6 chain hydrocarbon group; R1 represents an optionally substituted hydrocarbon group; and R2 and R3 each independently represents hydrogen, an optionally substituted hydrocarbon group or an optionally substituted heterocyclic group, or R2 and R3 may form an optionally substituted ring in cooperation with the adjacent nitrogen atom, or a salt of the compound. The pyrrolopyridine derivative has vanilloid receptor agonist activity and is useful as medicines such as a preventive/therapeutic agent and analgesic for overactive bladder.

Urea in formic acid is a general and practical reagent for the reductive aminoformylation of benzophenones and fluoren-9-one in the synthesis of N-diarylmethylformamides, which exhibit antispasmodic activity.With benzophenone in formic acid 1,3-dimethylurea gives a high yield of N-methyl-N-benzhydrylformamide.Urea reacts selectively with benzil and benzoin, forming both the bicyclic bisurea and monocyclic nitrogen-containing heterocycles, depending on the temperature.It was proposed for the first time to use arylmethylenebisureas as reagents in reaction with benzil for the production of 1,5-diphenyl-2,4,6,8-tetraazabicyclooctane-3,7-dione or 2,4,5-triphenylimidazole.
Evidence for rate limiting C-H bond cleavage in the leuckart reaction

A rho value of +0.21 is reported for the reaction of mono 4-substi- tuted benzophenones with formamide. This, in conjunction with a kinetic iso- tope effect value of 1.80 obtained for the system, suggests a rate-limiting C-H bond cleavage.
