実験手順

A solution of N-phenylpiperazine (30 mg, 0.185 mmol) in dichloromethane (2 mL) was treated with triethylamine (77 μL, 0.555 mmol), cooled to 0° C., treated with triphosgene (33 mg, 0.111 mmol), warmed to room temperature, stirred for 1 hour, treated with 4-({(1R)-3-(dimethylamino)-1-[(phenylthio)methyl]propyl}amino)-3-nitrobenzenesulfonamide (prepared according to the procedure described in commonly owned U.S. patent application Ser. No. 09/957,256, filed Sep. 20, 2001, 86 mg, 0.204 mmol) and DMAP (23 mg, 0.185 mmol), stirred overnight, and concentrated. The concentrate was purified by flash column chromatography on silica gel with 20% 2N NH3 in methanol/dichloromethaneto provide the desired product (46 mg, 41%). MS (ESI) m/e 613 (M+H)+; 1H NMR (500 MHz, CD3OD) δ 8.0–6.75 (13H, m), 4.15 (1H, m), 3.59 (2H, t), 3.39 (4H, m), 3.25 (4H, m), 3.16 (2H, t), 2.88 (6H, s), 2.35–2.15 (2H, m).
