2-(5-Methoxy-2-methylphenyl)-[1,3]dioxolane → 5-Methoxy-2-methylbenzaldehyde

Participants

Reaction Steps

A solution of 2-(2-methyl-5-methoxyphenyl)-1,3-dioxolane (4.2 g; 21.6 mmol; from step (ii) above) in a mixture of THF (60 mL) and HCl/aq (5%; 30 mL) was stirred overnight at room temperature. The solution was concentrated, and the mixture was extracted with ether. The organic phase was dried (Na2SO4) and concentrated yielding 2.956 g (91%) of a dark brown liquid.
