Methyl 5-(3,4,5,6-tetramethoxy-2-methylbenzyl)-2-benzyloxybenzoate (15.0 g, 32.1459 mmol) was dissolved in methanol (200 ml), added to a methanolic suspension (200 ml) of 10% palladium-carbon (1.0 g) 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 (11.2 g, 29.7340 mmol, 92%).
