Procedure

Methyl 3-bromo-4-hydroxy-5-(2-methylprop-2-en-1-yl)benzoate (5.0 g, 24.2 mmol) and 10% palladium-carbon (50% water-containing product, 1.5 g) were added to a mixed solvent of tetrahydrofuran (70 mL) and methanol (70 mL), and the mixture was stirred under a hydrogen atmosphere at room temperature for 5 hr. The catalyst was filtered off, and the filtrate was concentrated to give the title compound (4.8 g, yield 95%) as colorless needle crystals.

Workup

  1. filtrationThe catalyst was filtered off
