실험 절차

To a solution of 5-benzoyl-2-(1-tert-butoxycarbonyl-1H-thieno[3,2-c]pyrazol-3-yl)-indole-1-carboxylic acid tert-butyl ester [Intermediate (13)] in anhydrous tetrahydrofuran (5 mL) is added methylmagnesium bromide (1M in tetrahydrofuran, 0.8 mL) at −78° C. Stirred under nitrogen for 30 minutes. Added another 0.88 mL of methylmagnesium bromide and let the reaction warm to room temperature slowly. After overnight water/saturated ammonium chloride (2 mL) is added at 0° C. and extracted twice with ethyl acetate (25 mL). The combined ethyl acetate phases are washed with brine and dried over sodium sulfate. The residue is chromatographed on 10 g silica gel, eluting with 30 to 50% ethyl acetate gradient in heptane to afford 1-phenyl-1-[2-(1H-thieno[3,2-c]pyrazol-3-yl)-1H-indol-5-yl]-ethanol (56 mg, 71%, Example 26) as a beige solid; LC/MS: 360 (M+H); 1H NMR [(CD3)2SO)]: δ 13.20 (1H, s), 11.45 (1H, s), 7.73 (1H, d), 7.62 (1H, s), 7.43 (2H, m), 7.25 (6H, m), 6.59 (1H, s), 5.53 (1H, s), 1.86 (3H, s).
