Conditions for selective substitution for one chlorine atom in 2-(R,R′-amino)-4,6-dichloro-1,3,5-triazines with a hydroxide ion were elaborated. Spectral and calculation methods showed that the products formed are in the lactam form, i.e., have the structure of 4-chloro-6-(R,R′-amino)-1,3,5-triazin-2(1H)-ones.
