The general procedure for the synthesis of 4-tert-butyl-2,6-formylphenol from (5-(tert-butyl)-2-hydroxy-1,3-phenyl)dimethanol was as follows: activated MnO2 (40 g) was added to CHCl3 (200 mL) in a 500 mL round-bottom flask. The mixture was heated under stirring to reflux for about 15 minutes, then powder of (5-(tert-butyl)-2-hydroxy-1,3-phenyl)dimethanol (5.0 g) was added slowly. After keeping the reaction at reflux for 8 hours, the reaction mixture was cooled to room temperature and filtered through a Brinell funnel. The solid residue was washed thoroughly with CHCl3 (40 mL x 5) until the filtrate was colorless. The filtrates were combined and concentrated using a rotary evaporator to give the yellow solid product 4-tert-butyl-2,6-formylphenol (3.8 g, 77% yield).
