Chlorotrimethylsilane → Methyl 4-Formylbenzoate

Participants

Reaction Steps

The 4-carboxybenzaldehyde is of commercial origin. It is dissolved (3 g; 20 mmol) in a trimethylsilyl chloride solution (10 g; 92 mmol) in 100 ml of MeOH. The mixture is kept stirred for 40 h at room temperature. After evaporation, a white solid corresponding to 4-methoxycarbonylbenzaldehyde 24 is isolated, characterized by NMR and used as it is for the next reaction.
