ABSTRACT:
The process provided for the production of high-purity 1,3-bis-(.beta.-ethexyl)-5-amino-5-methyl-hexahydropyrimidine, also known as hexetidin, by reacting 1,3-bis-(.beta.-ethylhexyl)-5-nitro-5-methyl-hexahydropyrimidine with naphthalene-1,5-disulphonic acid in a solvent to selectively preciptitate the novel intermediate compound 1,3-bis-(.beta.-ethylhexyl)-5-nitro-5-methyl-hexahydropyrimidine-naphthale ne-1,5-disulphonate, which is separated off, treated with aqueous alkali to produce 1,3-bis-(.beta.-ethylhexyl)-5-nitro-5-methyl-hexahydropyrimidine, and subsequently hydrogenated to produce high-purity hexetidin.
