专利号:US-4749806-A 优先权日:1984-12-28 标题:Process for the synthesis of isocyanates and of isocyanate derivatives 发明人:TKATCHENKO IGOR; JAOUHARI RABIH; BONNET MICHEL; DAWKINS GORDON; LECOLIER SERGE 权利人:POUDRES & EXPLOSIFS STE NALE 摘要:The present invention relates to a process for the synthesis of isocyanates and of isocyanate derivatives. Isocyanates are obtained by reacting an organic halide with a metal cyanate in an organic medium in the presence of a catalyst consisting of a complex of nickel with at least one organic ligand, in which complex the nickel is in the zero oxidation state. A carbamate or a urea, respectively, are obtained by a subsequent reaction with a hydroxy compound or a primary or secondary amine. Isocyanates and their derivatives are used especially either as refined synthesis agents for the production of pesticides and medications, or as monomers or comonomers for the preparation of many macromolecular compounds.

This polymorph is useful in pharmaceutical compositions, for example, for the treatment and prevention of migraine. The invention also provides a process for the synthesis of pyridinoylpiperidine compounds of Formula I in high yield and high purity. In particular, the provides a process for the preparation of 2,4,6-trifluoro-N-[6-(1-methyl-piperidine-4-carbonyl)-pyridin-2-yl]-benzamide, its hemisuccinate salt and polymorph (Form A).
