실험 절차

A mixture of 6-(3-bromo-propoxy)-2-(1-tert-butoxycarbonyl-5-phenyl-1H-thieno[3,2-c]pyrazol-3-yl)-indole-1-carboxylic acid tert-butyl ester [300 mg, 0.460 mmol, Intermediate 50)], piperidine (60.2 mg, 0.707 mmol), potassium carbonate (191 mg, 1.38 mmol), potassium iodide (40.0 mg, 0.241 mmol), and anhydrous acetonitrile (5.0 mL) was heated at 70° C. with shaking at 200 rpm. After 20 hours, the reaction was cooled to ambient temperature, filtered, the insolubles washed three times with dichloromethane (5 mL), and the filtrate concentrated under reduced pressure to give a dark residue. The residue was chromatographed on silica, eluting with 10%-1 M ammonia in methanol/90% dichloromethane, to give 2-(1-tert-butoxycarbonyl-5-phenyl-1H-thieno[3,2-c]pyrazol-3-yl)-6-[3-(piperidin-1-yl)-propoxy]-indole-1-carboxylic acid tert-butyl ester (310 mg) as a brittle green foam: LC/MS: 657.3, (M+H), RT=3.92 minutes, 50% UV purity). A mixture of this material (300 mg), 4 M aqueous potassium carbonate (5.0 mL), tetrahydrofuran (5.0 mL) and methanol (5.0 mL) was heated at 60° C. for 2 hours. After cooling to room temperature, the solvent was removed in vacuo to give a solid. The crude solid was suspended in water (25 ml) and the mixture stirred at room temperature for 0.5 hours. The solid was collected by filtration and dried to give a grey solid. Trituration of the solid with 20% methanol/ether provided 2-(5-phenyl-1H-thieno[3,2-c]pyrazol-3-yl)-6-(3-piperidin-1-yl-propoxy)-1H-indole [90.0 mg, 43%, Example 58] as a grey solid. TLC Rf 0.37 (silica, 14% 1 M ammonia in methanol/86% dichloromethane); LC/MS: 457.3 (M+H), RT=2.93 minutes; 1H NMR [300 Mhz, (CD3)2SO]: δ 13.30 (br s 1H), 11.39 (br s, 1H), 7.78 (d, J=7 Hz, 2H), 7.64 (s, 1H), 7.49-7.35 (m, 4H), 6.92 (s, 1H), 6.65 (d, J=8.5 Hz, 1H), 6.59 (s, 1H), 3.98 (t, J=6 Hz, 2H), 2.43-2.33 (m, 6H), 1.88 (m, 2H), 1.50-1.39 (m, 6H).
