Participants

Reaction Steps

Methyl 4-formylbenzoate (1.28 g, 7.83 mmol) was added to a solution of 1-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-naphthalen-2-yl)-ethanone (Compound 1, 1.80 g, 7.83 mmol) in 10 mL of 1 N NaOH and 20 mL of methanol. After stirring at room temperature for 18 h, the reaction mixture was acidified with 1N HCl and extracted with ethyl acetate (3×10 mL). The combined organic layer was washed with brine (1×10 mL), dried (MgSO4) and concentrated at reduced pressure. Recrystallization (acetonitrile) gave the title compound (1.70 g, 60% yield) as a white solid:
