Sodium Iodide → HCID 18366184, compound

Participants

Reaction Steps

A mixture of 12.7 g (85 mmol) of sodium iodide in 425 mL of dry acetonitrile was prepared under nitrogen in a predried 2 L flask and to this mixture 9.25 g (10.8 mL, 85 mmol) of chlorotrimethylsilane was added by means of a syringe at ambient temperature with stirring. After 10 min, 17.0 g (85 mmol) of 2-amino-8-chloro-5-methoxy[1,2,4]triazolo[1,5-c]pyrimidine and 8.62 g (11.9 mL, 85 mmol) of triethylamine were added with stirring. The mixture was allowed to react for 12 hours at ambient temperature with stirring and was then diluted with 500 mL of dry diethyl ether. The salts that precipitated were removed by filtration on a dry scintered glass filter and the filtrate was concentrated by evaporation under reduced pressure. The residue was diluted with another 500 mL of dry diethyl ether the salt removal procedure was repeated. The title compound was obtained as the solid residue and amounted to 19.5 g (84 percent of theory).
