N-[5-(3,4,5,6-Tetramethoxy-2-methylbenzyl)-2-benzyloxybenzoyl]morpholine (1.27 g, 2.59 mmol) was dissolved in ethanol (50 ml) and the resulting solution was added to an ethanol suspension (5 ml) of 5% Pd—C (0.200 g) and stirred at room temperature for 16 hours in a hydrogen stream. The reaction solution was filtered, the filtrate was concentrated and the obtained residue was recrystallized from ether to obtain the titled compound (1.00 g, 2.49 mmol, 96%).
