Benzyl 3-methoxy-4-(2-methyl-1-oxopropan-2-yl)benzoate (crude, from step 2) was then treated with MeOH (2 mL) followed by NaBH4 (190 mg, 5.03 mmol). The reaction mixture was stirred for 1 h before it was quenched with brine and extracted with EtOAc. The organic layers were combined, dried over sodium sulfate, and evaporated to give benzyl 4-(1-hydroxy-2-methylpropan-2-yl)-3-methoxybenzoate.
