Abstract
By the method 2-substituted 4,6-diamino-5-cyanopyrimidines with the formula where R1 means hydrogen, C2-C6-alkyl, C2-C6-alkenyl or C2-C6-alynyl and R2 is hydrogen, C1-C10-alkyl or C3-C6-cycloalkyl, or R1 and R2 together mean radical, q selected from the group -(CH2)3-, -(CH2)4- and -(CH2)5-, are produced as dialkylcyanimidocarbonate having the formula where R3 and C1-C4-alkyl, reacts with the alkalimetallic salts of malononitrile or with malononitrile and alkalimetallic base at temperatures form -10 to 40°C. Alkalimetallic salt of 1-alkoxy-1-cyanamino-2,2-dicyanoethylene is produced having the formula where R3 is C1-C4-alkyl and M+ is alkalimetallic cation. The compound produced reacts with excess ammonia at temperature range from 60 to 100°C, producing alkalimetallic salt of 1-amino-1-cyanamino-2,2-dicyanoethylene with the formula where M+ is alkalimetallic cation. This salt reacts with hydrogen chloride excess in secondary alcohol, water, or a mixture thereof as solvent, where 2-chloro-4,6-diamino-5-cyanopyrimidine is produced reacting with amine having the formula R1R2NH where R1 and R2 have the meanings defined in formula I where the end product is turned out.
