N-[5-(3,4,5,6-Tetramethoxy-2-methylbenzyl)-2-benzyloxybenzoyl]piperidine (1.02 g, 2.09 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 (0.760 g, 1.95 mmol, 93%).
