| titleOfInvention | Process for preparing 2,6-dihydroxymethylpyridine bis (N-methylcarbamate) |
| abstract | The present invention relates to a process for the preparation of 2,6-dihydroxymethylpyridine bis (N-methylcarbamate),nwhich is carried out by allowing it to reactn2,6-dihydroxymethylpyridine hydrochloridenwith tertiary methyl isocyanate, tetrahydrofuran,nacetonitrile or halonhydrocarbon, in the presence of at leastnone equivalent, calculated on the hydrochloride,na tertiary amine, preferably a trialkylaminenor a cyclic tertiary amine,nnitrogen-substituted alkylnwith 1 to 4 carbon atoms, the reaction mixture is stirrednthe crude product is recrystallizednfirst from water, then from the mixturenmethanol or ethanol and water, preparednin a ratio of 1: 1 to 1: 2, this beingnthe mixture is used in four to six timesnamount, calculated on recrystallizednthe product, and the product obtained is dried at room temperaturentemperature of 50 to 100 ° C.n2,6-dihydroxymethylpyridine bis (N-methylcarbamatenis widely used in medicinento treat vascular diseases |
