4-bromo-2-methoxybenzaldehyde Usage And Synthesis

Chemical Properties

off-white solid

Uses

4-Bromo-2-methoxybenzaldehyde is used in the building block, synthesis of a nonacid degradable linker for solid-phase synthesis. It is a useful intermediate in the chemical industry.

Synthesis

A synthesis of 4-bromo-2-methoxybenzaldehyde is reported from 1,4 dibromo 2-fluorobenzene. First, 2-fluoro-4-bromobenzaldehyde is prepared through metal halogen exchange and formylation with a formyl source at 0° C. After crystallization, this intermediate is reacted with methanol in the presence of potassium carbonate. Subsequently, 4-bromo-2-methoxy-benzaldehyde is crystallized.
