Versuchsvorschrift

A solution of 1.25 ml (8.05 mmol) of diethyl azodicarboxylate in 7 ml of THF is added in drops to a stirred solution of 2.60 g (7.66 mmol) of 8-hydroxymethyl-5-(4-nitrophenyl)-9H-1,3-dioxolo[4,5-h][2,3]-benzodiazepine (starting compound III.), 2.11 g (8.05 mmol) of triphenylphosphine and 1.18 g (8.05 mmol) of phthalimide in 130 ml of dry THF at room temperature. The mixture is stirred for 24 hours at this temperature. Then, the precipitated product is suctioned off and washed with ethanol. 2.87 g (80%) of the title compound, which can be further processed without further purification, is obtained.
