Synthesis and N-methylation of tetrabutylammonium isocyanurate

A simple and efficient method for the synthesis of ammonium salt of isocyanuric acid is set out. This process is based on the direct addition of the corresponding hydroxide to isocyanuric acid. This salt exhibits several interesting properties. Its alkylation by iodomethane in various solvents is demonstrated and leads to various substituted isocyanurate derivatives.
