実験手順

To a solution of 1-[5-(2-phthalimidoethanesulfonamido)indole-2-carbonyl]-4-[N-methyl-N-(3-(1-methylethylamino)-2-pyridinyl)amino]piperidine (EXAMPLE 31, 675 mg) in 95% ethanol (10 ml) under nitrogen is added hydrazine monohydrate (53 μl). The mixture is stirred at 70°-750° for 20 hrs during which additional hydrazine monohydrate (10 μl) is added, concentrated to remove ethanol, diluted with water (10 ml), acidified to pH 2 with 1M hydrochloric acid and stirred for 10 min. The mixture is then filtered, the filtrate is adjusted to pH 10-11, and the resulting precipitate is isolated by filtration to give the title compound, NMR (CDCl3) 9.86, 7.70, 7.56, 7.29, 7.10, 6.94, 6.84, 6.68, 4.60, 4.50, 3.56, 3.44, 3.40-2.80, 2.62, 1.93, 1.65 and 1.22 δ. The b&sic filtrate is extracted with methylene chloride (2×15 ml) which is then washed with saline (10 ml), dried over sodium sulfate, and concentrated under reduced pressure to give an additional amount of the title compound.
