Versuchsvorschrift

Added to a solution of 39 mg (0.050 mmol) of 1,4-bis[5-nitro-2-(3,4,5-trimethoxy-phenyl)benzoyl]hexahydro-1,4-diazepine synthesized by the process described in Example 71 in acetic acid-ethyl acetate (3:2, 2.5 ml) were 39 mg of 10% palladium on carbon, and the mixture was stirred for 2 hours at room temperature under hydrogen. The catalyst was removed from the reaction mixture by suction filtration through Celite, and the filtrate was concentrated under reduced pressure. A chloroform solution of the residue was washed with a saturated aqueous solution of sodium hydrogencarbonate and a saturated saline solution, dried over anhydrous sodium sulfate and then concentrated under reduced pressure. The resultant crude oil was purified by column chromatography on silica gel to obtain 32 mg (yield: 90%) of the title compound as a pale yellow amorphous powder.
