Synthesis of R-Salt (CTMTNA)

First, a blue nitrous acid solution is made by diluting 30 mL of conc. HCl with 50 mL of water and combining it with 18 g of potassium nitrite dissolved in 30 mL of water. The nitrous acid solution in a beaker is immersed in an ice bath until the temperature is below 0°C. Then a fast addition of 7 g of hexamine dissolved in 50 mL of water is started.
