METHYL SULFANYL PYRMIDMES USEFUL AS ANTIINFLAMMATORIES, ANALGESICS, AND ANTIEPILEPTICS
-
Page/Page column 144, (2010/12/18)
The present invention relates to pyrimidine derivatives of Formula (Ia) and (Ib) (including tautomers, isomers, prodrugs, and pharmaceutically acceptable salts thereof). Said compounds are useful in the treatment of pain (such as neuropathic pain), inflammation, and epilepsy (by acting as anticonvulsants). Methods of medical treatment making use of said compounds, as well as additional compounds of Formula (IIa) and (IIb), are also disclosed.
Development of an efficient process towards the benzimidazole BYK308944: A key intermediate in the synthesis of a potassium-competitive acid blocker
Webel, Matthias,Palmer, Andreas Marc,Scheufler, Christian,Haag, Dieter,Mueller, Bernd
experimental part, p. 142 - 151 (2010/04/29)
An entirely new synthesis of the important benzimidazole building block BYK308944 was elaborated using the Stobbe reaction as central element. BYK308944 constitutes an important intermediate for the preparation of 3,6,7,8-tetrahydrochromeno[7,8-d] imidazoles as potassium-competitive acid blockers. The new route relies on the hydroxymethylation of 1,2- dimethylimidazole as cheap starting material followed by oxidation of the corresponding alcohol and Stobbe condensation of the resulting aldehyde with diethyl succinate. All synthetic steps of this new approach were optimized particularly with the goal to establish a process amenable for large- scale preparation.
Reactions of 1,2-Dimethylimidazole, Particularly its Metallation
Iddon, Brian,Lim, Bee Lan
, p. 271 - 277 (2007/10/02)
A re-examination of the metallation of 1,2-dimethylimidazole has shown that, after quenching of reaction mixtures with suitable reagents, single products may arise from substitution either in the 2-methyl group or in the 5-position or mixtures of both products may arise, depending on the metallating reagent, solvent, and reaction conditions. 1,2-Dimethylimidazol-5-yl-lithium was prepared by reaction of 1,2-dimethyl-5-trimethylstannylimidazole (13) with n-butyl-lithium in tetrahydrofuran at -100 deg C.The corresponding 5-trimethylsilyl compounds (12) was metallated by n-butyl-lithium exclusively in the 2-methyl group. 1,2-Dimethylimidazol-5-yl-lithium was shown to undergo transmetallation reactions at temperatures higher than -100 deg C.An improved procedure is given for the synthesis of 1,2-dimethylimidazole-5-carbaldehyde via hydroxymethylation of 1,2-dimethylimidazole and oxidation of the 5-hydroxymethyl group with nitric acid.
