実験手順: The compound was prepared from 2-amino-5-(4-t-butyloxycarbonyl-1-homopiperazinyl)aniline and 3-flourobenzenesulfonyl chloride. Purification by column chromatography (CH2Cl2/MeOH/heptane, 4:1:15) gave a mixture of N-{2-amino-4-[4-t-butyloxycarbonyl-homopiperazin-1-yl-]phenyl}3fluorobenzenesulfonamide and N-{4-[4-t-butyloxycarbonyl] homopiperazinyl)-2-[(3-flourophenylsulfonyl)amino]phenyl}-3-fluorobenzenesulfonamide (0.180 g, 73%). Boc-deprotection was achieved by dissolving the mixture in small amount of MeOH and adding HCl/ether. The mixture was let at r.t. for 0.5 h. Purification by preparative HPLC gave N-(4-(1,4-diazepan-1-yl)-2-{[(3-fluorophenyl)sulfonyl]amino}phenyl)-3-fluorobenzenesulfonamide hydrochloride Anal.

実験手順: 3-fluorobenzenesulfonamide (250 mg, 1.4 mmol), 2,3-dichloroquinoxaline (284.1 mg, 1.4 mmol) and dry K2CO3 (198.4 mg, 1.4 mmol) are dissolved in dry DMF (0.8 ml) and heated up to 135° C. in a sealed tube for 2.5 h. When TLC confirms the completion of the reaction, the reaction mixture is cooled down to rt and quenched by addition of water (4 ml) and AcOH (0.03 ml). The residue obtained is triturated and the resulting solid is filtered and washed with water until neutral pH then dried under vacuum to afford 400 mg (83%) of the title compound as an off white solid. 1H NMR (DMSO-d6) δ 12.8-10.9 (br s, 1H), 8.05-7.62 (m, 7H), 7.54 (td, J=2.0, 8.5 Hz, 1H).
