Reaction Steps

A solution of 5 g (14.8 mmol) of 1-(chloromethyl)-5,8-dimethyl-3-phenyl-3,5-dihydro-4H-pyridazino[4,5-b]indol-4-one, of 2.7 g (55 mmol) of sodium cyanide and of 0.5 g (3 mmol) of sodium iodide in a mixture of 50 ml of dimethylformamide and of 30 ml of water is stirred for 2 h at 50° C. The mixture is left standing at room temperature and the precipitate is collected by filtration. It is washed with water and with pentane and is dried under reduced pressure. 3 g (9.1 mmol) of product are obtained, which product is used as is in the following stage.
