Discovery of 2-(2-chlorophenyl)-3-(4-chlorophenyl)-7-(2,2-difluoropropyl)- 6,7-dihydro-2H-pyrazolo[3,4-f][1,4]oxazepin-8-(5H)-one (PF-514273), a novel, bicyclic lactam-based cannabinoid-1 receptor antagonist for the treatment of obesity
We report the design, synthesis, and structure-activity relationships of novel bicyclic lactam-based cannabinoid type 1 (CB1) receptor antagonists. Members of these series are potent, selective antagonists in in vitro/in vivo efficacy models of CB1 antagonism and exhibit robust oral activity in rodent models of food intake. These efforts led to the identification of 19d, which has been advanced to human clinical trials for weight management.

Process for Preparing Bicyclic Pyrazolyl
A process for preparing compounds of Formula (I) is described herein. The compounds have been shown to act as cannabinoid receptor ligands and are therefore useful in the treatment of disease linked to the mediation of the cannabinoid receptors in animals.
