This invention relates to methods of making pyrimidinyl-substituted imidazole compounds by sequential substitution of the 4- and 2-chloro groups of 2,4-dichloropyrimidine, nucleophilic substitution to form pyrimidinylalkyne derivatives, oxidation to the corresponding 1,2-diketones, and cyclocondensation reactions.
Disclosed are compounds of Formulae 1 and 1a, N-oxides, and salts thereof,
wherein
R1, R1a, Y, and J are as defined in the disclosure.
Also disclosed are compositions containing the compounds of Formula 1 and methods for controlling plant disease caused by a fungal pathogen comprising applying an effective amount of a compound or a composition of the invention. Further disclosed is a method for preparing compounds of Formula 1 from compounds of Formula 1a.

4-Aryl-5-pyridyl and 4-aryl-5-pyrimidyl based inhibitors of TNF-alpha production, which contain a novel triazole 5-member heterocyclic core, are described. Many pyridyl triazoles containing either an alkyl ether or a substituted aryl side chain on the triazole core showed sub-micromolar activity against LPS-induced TNF-alpha, while pyrimidyl triazoles containing an ethoxymethyl side chain exhibited even better inhibitory activity. Secondary screening data are presented for the pyrimidyl triazoles. Triazole 14e combined excellent potency with good oral bioavailability in the rat. (C) 2003 Elsevier Science Ltd.
