Reaction Steps
In 20 ml of ethanol were dissolved 1.2 g of 2-aminothiazole and 3.9 g of 3,5-di-tert-butyl-4-hydroxyphenacyl bromide, and the solution was refluxed for 2 hours. The reaction mixture was neutralized by the addition of aqueous ammonia and added 30 ml of water. The crystals thus precipitated were recovered by filtration and recrystallized from ethanol to provide 1.5 g of 6-(3,5-di-tert-butyl-4-hydroxyphenyl)imidazo[2,1-b]thiazole.
