| abstract | The present invention provides intermediate 2 (2,3-dichlorophenyl) -2 of the formula (II) comprising reacting 2,3-dichlorobenzoyl cyanide with an aminoguanidine bicarbonate in the presence of methanesulfonic acid in a non-aqueous medium. A method for preparing-(aminoguanidine) acetonitrile, wherein the reaction provides excellent yield and short reaction time. Such intermediates are useful for the preparation of 3,5-diamino-6- (2,3-dichlorophenyl) -1,2,4-triazine of formula (I). The invention also relates to a process for the preparation of compounds of formula (I) in high purity.n n n Formula In n n n n n n n Formula II |
