Versuchsvorschrift

A suspension of the 6-benzyloxypyranoindole (5.4 g, 13.25 mmol) of Step A, and 10% Pd/C catalyst (600 mg) in ethanol (150 mL) is hydrogenated for 6 hours in a Parr shaker. Filtration of the catalyst and evaporation of the solvent affords the title compound (3.75 g, 89%) as a cream-colored foam homogeneous by TLC.
