Hydrochloric Acid → HCID 13107023, compound

Participants

Reaction Steps

To a mixed solution of 1.2 g of 4-(2-aminoacetyl)-2,6-di-tert-butylphenol hydrochloride, 10 ml of ethanol, and 0.3 ml of concentrated hydrochloric acid was added a solution of 0.64 g of potassium isocyanate in 3 ml of water at room temperature. After stirring the mixture for 2 hours, 0.3 ml of concentrated hydrochloric acid was added thereto and the resultant mixture was refluxed for 2 hours. The reaction mixture thus obtained was poured into water and the precipitates formed were recovered by filtration. The reaction product was then recrystallized from aqueous ethanol to provide 0.5 g of 4-(3,5-di-tert-butyl-4-hydroxyphenyl)-2-oxo-4-imidazoline.
