実験手順

Methylmagnesium bromide (0.23 ml of a 3M solution in diethyl ether) was added dropwise to a stirred solution of N6-methoxy-N6,1-dimethyl-3-{1-(1,3-benzodioxol-5-yl)-2-[(4-methylphenyl)sulfonamido]-2-oxoethyl}-1H-6-indolecarboxamide (from Example 103, 174 mg, 0.32 mmol) in anhydrous tetrahydrofuran (5 ml) at −70° C. under a nitrogen atmosphere. The mixture was stirred at −70° C. for an additional 2 hours before warming to room temperature. Aqueous hydrochloric acid (5 ml of 1M solution) was slowly added to the mixture, and then it was extracted with ethyl acetate (100 ml). The organic phase was separated and washed with brine, dried (magnesium sulphate) and the solvent were removed in vacuo. The residue was flash chromatographed using a gradient elution of a mixture of 90% hexane and 10% ethyl acetate, through to 100% ethyl acetate, to give the title compound (18 mg).
