Hydrochloric Acid → HCID 178448769, compound

Participants

Reaction Steps

Combined solutions of 50.0 g (0.435 mol) tert-butyl isothiocyanate in 125 ml ethanol and 56.6 g (0.850 mol) sodium azide in 900 ml water were heated under reflux with stirring for 5.5 hours. After cooling, the solution was acidified to pH 1 with hydrochloric acid and extracted with ether. The extracts were washed with water and aqueous saturated sodium chloride solution, dried over magnesium sulfate, and evaporated to yield 21 g of colorless oil which later crystallized. The product of a repeat of this preparation was triturated with ligroine to yield colorless crystals of Ia mp 92°-94°, confirmed by NMR, infrared, and mass spectral data as well as elemental analysis.
