摘要： It comprises a preparation process of Montelukast from a new intermediate compound of formula (VI), which is previously prepared by reaction of the corresponding sulfonate with 1-(mercaptomethyl)cyclopropyl)methanol. Compound (VI) is reacted with a Grignard reactant to convert the ester group into a tertiary alcohol, followed by conversion of the primary alcohol into a sulfonate, substitution of the sulfonate group by a cyano group, and finally transforming the cyano compound to the carboxilic acid compound by a hydrolysis reaction to afford Montelukast. Montelukast can also be prepared by a hydrolysis reaction of the corresponding amide. It also comprises new intermediate compounds useful in such preparation process.

摘要： Process for the preparation of optically active derivatives of 2-(2-piridylmethylsulfinyl)-benzimidazole, or salts thereof, by resolution of the corresponding racemic derivatives of 2-(2-piridylmethylsulfinyl)-benzimidazole. The resolution is performed through the formation of inclusion complexes with (S)-(−) or (R)-(+)-[1,1′-Binaphthalene]-2,2′-diol in the presence of an amine, followed by the break of the inclusion complex by treatment with an hydroxide of an alkaline metal. The enantiomer of the derivative of 2-(2-piridylmethylsulfinyl)-benzimidazole may be obtained by extractions at a particular pH with a suitable organic solvent. The process allows to perform the resolution with high yields and high optical purity, without using neither toxic solvents nor chromatography.
