실험 절차

To a solution of 1-[5-aminoindole-2-carbonyl]-4-[3-(1,1-dimethylpropylamino)-2-pyridinyl]piperazine (EXAMPLE 41, 300 mg) in dry methylene chloride (6 ml) under nitrogen is added pyridine (119 μl) and methanesulfonyl chloride (57 μl). The mixture is stirred at 20°-25° for 24 hr and then diluted with methylene chloride (20 ml) and water (8 ml). The layers are separated and the organic phase is washed with saline (8 ml), dried over sodium sulfate, and concentrated to give a solid which is then chromatographed on silica gel (230-400 mesh, 34 g, 5-6 psi), eluting with methanol/chloroform (2.5/97.5). Pooling of the appropriate fractions, concentration to a solid, and recrystallization from chloroform gives the title compound, mp 232°-233° (decomp).
