How is tert-butyl 4-hydroxy-3-MethoxybenzylcarbaMate (CAS: 130972-89-3) typically synthesized?

Tert-butyl 4-hydroxy-3-MethoxybenzylcarbaMate is commonly synthesized through a multi-step process involving the protection of a hydroxyl group followed by a benzyl substitution reaction. The synthesis typically uses tert-butyldimethylsilyl chloride as a protecting agent and catalytic amounts of a Lewis acid such as BF3•OEt2 to facilitate the benzylation step. The yield and selectivity can be optimized through careful choice of reaction conditions.
