REGIO-SELECTIVE SYNTHESIS OF IMIDAZO[1,2-A]PYRIMIDINES

Paragraph 0067; 0082, (2020/11/23)
A method of regio-selectively synthesizing an imidazo-pyrimidine compound of formulae (XXa) or (XXb) comprising a step of coupling a first compound of formula XX-P1a or XX-P1b with a second compound of formula XX-P2. This annulation reaction between β-ethoxy acrylamides and phosphorylated aminoimidazoles to furnish imidazo[1,2-a]pyrimidin-amines relies on steering effects from endocyclic and exocyclic phosphorylated aminoimidazoles. The reaction furnishes either 2-amino or 4-amino constitutional isomers of imidazo[1,2-a]pyrimidines with good yields and ranges of 90:10 – 99:1 regio-selectivity. The reaction is useful in the synthesis of various tracer molecules used in the study of neurological conditions such as where R3 and R4 together with the imidazole ring atoms to which they are bonded form a phenyl ring and the products are substituted benzimidazopyrimidines. The reaction can be generalized to form imidazo[1,2-a]pyrimidines substituted at either of their 2- and 4- positions by alkoxy or thioalkyl groups.

The structure-activity relationships for a series of heteroaryl urea inhibitors of fatty acid amide hydrolase (FAAH) are described. Members of this class of inhibitors have been shown to inactivate FAAH by covalent modification of an active site serine with subsequent release of an aromatic amine from the urea electrophile. Systematic Ames II testing guided the optimization of urea substituents by defining the structure-mutagenicity relationships for the released aromatic amine metabolites. Potent FAAH inhibitors were identified having heteroaryl amine leaving groups that were non-mutagenic in the Ames II assay.
HETEROARYL-SUBSTITUTED UREA MODULATORS OF FATTY ACID AMIDE HYDROLASE

Page/Page column 32-33, (2010/07/02)
Certain heteroaryl-substituted piperidinyl and piperazinyl urea compounds are described, which are useful as FAAH inhibitors. Such compounds may be used in pharmaceutical compositions and methods for the treatment of disease states, disorders, and conditions mediated by fatty acid amide hydrolase (FAAH) activity, such as anxiety, pain, inflammation, sleep disorders, eating disorders, insulin resistance, diabetes, osteoporosis, and movement disorders (e.g., multiple sclerosis).
