, p. 6985 - 6988 (2009)
A practical synthetic route to 2-substituted aminophenyl and hydroxyphenyl pyridines has been developed. It has been accomplished by the cross-coupling reactions of readily available 2-pyridylzinc bromides with haloaromatic amines and alcohols under mild

Paragraph 69; 126; 128, (2018/12/02)
The present invention provides novel diarylurea derivatives (compounds of formula (I)) and their uses. The compounds of the present invention are demonstrated to be allosteric modulators of the CB1 receptor, and therefore useful for the treatment of diseases and conditions mediated by CB1.

Allosteric modulators of the cannabinoid CB1 receptor have recently been reported as an alternative approach to modulate the CB1 receptor for therapeutic benefits. In this study, we report the design and synthesis of a series of diarylureas derived from PSNCBAM-1 (2). Similar to 2, these diarylureas dose-dependently inhibited CP55,940-induced intracellular calcium mobilization and [35S]GTP-γ-S binding while enhancing [3H]CP55,940 binding to the CB1 receptor. Structure-activity relationship studies revealed that the pyridinyl ring of 2 could be replaced by other aromatic rings and the pyrrolidinyl ring is not required for CB1 allosteric modulation. 34 (RTICBM-74) had similar potencies as 2 in all in vitro assays but showed significantly improved metabolic stability to rat liver microsomes. More importantly, 34 was more effective than 2 in attenuating the reinstatement of extinguished cocaine-seeking behavior in rats, demonstrating the potential of this diarylurea series as promising candidates for the development of relapse treatment of cocaine addiction.

scheme or table, p. 3135 - 3146 (2010/06/13)
A facile synthetic approach to the direct preparation of 2-pyridyl and 3-pyridylzinc bromides has been demonstrated using Rieke zinc with 2-bromopyridine and 3-bromopyridine, respectively. A variety of different electrophiles have been coupled with the resulting organozinc reagents to give the corresponding cross-coupling products in moderate to good yields.
