摘要:
This invention involves a coupling reaction involving an organo-metallic catalyst, preferably a palladium catalyst involving reacting 2-halo-3-hydroxy-6-hydroxymethylpyridine, acrylic acid or its alkali metal salt and benzyl or a phenylalkyl derivative in presence of a dipolar aprotic solvent producing none other than the expected 2-propenoate-3-benzyl or phenylalkylether-6-hydroxymethyl-pyridine product. Said products are converted into medicaments useful for treating psoriasis.

摘要:
The process of this invention for preparing Mn(II) chelate comprises forming the Mn(II) chelate by mixing manganese (II) oxide (insoluble) with an aqueous suspension comprising a molar equivalent or molar excess of the insoluble protonated chelating compound at a temperature of from 20.degree.to 50.degree. C. When the reaction is carried out with a protonated chelating agent in the absence of base, a precipitate of the protonated Mn(II) chelate is formed. A low osmolarity MN(II) chelate solution can be formed from the precipitates by dissolving them in an aqueous solution of base. When the initial chelate forming reaction is carried out in a solution containing a molar equivalent or excess of sodium hydroxide, a low osmolarity solution of the Mn(II) chelate is directly formed with most chelating agents. Preferred chelating compounds for this process include DPDP, DTPA, DCTA, EDTP, DOTA, DOXA, DO3A and EDTA. The Nm(II) chelate precipitates and low osmolarity solutions formed by the above processes are also aspects of this invention.
摘要:
The esters of pyridoxine and of isopropylidene pyridoxine with 1-(p-chlorobenzoyl)-2-methyl-5-methoxy-indol-3-acetic acid and 5-(2,4-difluorophenyl)-salicylic acid are essentially endowed with the same activities of the corresponding acids and are less toxic and gastrolesive, whereby the therapeutical index is remarkably improved. For the preparation of these compounds the chloride of the acid is reacted with isopropylidene pyridoxine, followed by a hydrolysis to obtain the corresponding pyridoxine derivative.
