    Abstract: The 2-[2-(3,5-dichlorophenyl)ethyl]benzoic acid (V) which is the key intermediate for the preparation of eberconazol (I) through a known sequence of four steps is prepared by catalytic hydrogenation of 2-[2-(3,5-dichlorophenyl)ethenyl]benzoic acid (VI). The intermediate (VI) is prepared by hydrolysis of its methyl ester obtained by a Wittig reaction between 3,5-dichlorobenzaldehyde and the ylure of phosphor of the bromide of [[(2-metoxycarbonyl)phenyl]-methyl]triphenylphosphonium. The global process can be easily increased in scale since the reactions can be carried out at moderate temperature without requiring a strictly inert atmosphere and without any risk of inflammation. The carboxylic acid (VI) and its methyl ester are chemically new intermediates. The invention is useful for the industrial preparation of the antifongic agent eberconazol (I).

    Abstract: Pharmaceutical formulation obtainable subjecting conventional microgranules to an external seal-coating layer that avoids the penetration of liquid vehicle, and selecting a hydrophobic liquid vehicle with a viscosity high enough not to wet the microgranules. The seal-coating layer may be obtained by coating the microgranules with an aqueous suspension comprising film formers and plasticizers. The liquid vehicle is comprised of oily solvents, and viscosity agents. The formulation is presented in single dose sachets ready-to-use. This formulation enables the liquid oral administration of antiulcerous microgranules of benzimidazoles (omeprazole, lansoprazole, pantoprazole, rabeprazole), with several advantages comparing to commercially available extemporaneous suspensions. The new formulation of lansoprazole microgranules has a similar bioavailability and slightly higher stability than conventional hard gelatin capsules.
