Методика

A solution of 10 grams of 2,6-di-tert-butyl-4-mercaptophenol and 2.3 grams of cyclohex-3-enyl carboxaldehyde is charged to a flame-dried flask and treated with 1.0 ml of tetrafluoroboric acid and stirred for two hours. The reaction mixture is extracted with aqueous sodium bicarbonate and dried over anhydrous magnesium sulfate. The solvent is stripped in vacuo, and the residue recrystallized from acetonitrile to give 9.0 grams (76% yield) of white crystals, mp 122°-125° C.
