Procedure

Methyl 3-(3,4,5,6-tetramethoxy-2-methylbenzyl)-2-benzyloxybenzoate (343 mg, 0.7360 mmol) was dissolved in methanol (10 ml), added to a methanolic suspension (40 ml) of 10% palladium-carbon (100 mg) and stirred for 16 hours at room temperature in a hydrogen atmosphere. The reaction solution was filtered and the filtrate was concentrated under reduced pressure to give the title compound (223 mg, 0.5930 mmol, 81%).
