Reaction Conditions

Reaction Steps

A mixture of 4.5 g of formamide and 2.25 g of 4-(2-bromopropionyl)-2,6-di-tert-butylphenol was heated to 150° C. for 1.5 hours. The reaction mixture was poured into water after cooling and then extracted twice each time with 30 ml of toluene. The extract was dried over anhydrous magnesium sulfate and concentrated under reduced pressure and the residue was recrystallized from aqueous methanol to provide 1.1 g of 4-(3,5-di-tert-butyl-4-hydroxyphenyl)-5-methyloxazole.
