How is 3-(Cyclopropylmethoxy)-4-hydroxybenzaldehyde (CAS: 25934-52-5) typically synthesized?

3-(Cyclopropylmethoxy)-4-hydroxybenzaldehyde (CAS: 25934-52-5) is typically synthesized via a multi-step process involving the protection of a hydroxyl group, subsequent alkylation, and deprotection. Key steps include the use of acetone as a solvent, and the reaction is often catalyzed by Lewis acids. High selectivity and yield are achieved under optimized reaction conditions.
