実験手順

The preparation is carried out as in Example 3.2, from 3.1 g (7.5 mmol) of 9-bromo-5-methyl-4-oxo-3-phenyl-3,5-dihydro-4H-pyridazino[4,5-b]indole-1-acetic acid, from 1.4 g of 1,1′-carbonylbis-1H-imidazole and from 0.7 ml of pyrrolidine. After reaction, water is added and the precipitate is collected by filtration and dried under reduced pressure. It is recrystallized from propan-2-ol and washed with ether and pentane. It is dried under reduced pressure. 2.3 g (4.9 mmol) of solid are obtained.
