Versuchsvorschrift

Sodium borohydride (9 mg) was added to s suspension of 6-formyl-3-{1-(7-methoxy-1,3-benzodioxol-5-yl)-2-[(2-methoxy-4-methylphenyl)sulfonamido]-2-oxoethyl}-1-methyl-1H-indole (from Example 96, 130 mg, 0.24 mmol) in a mixture of ethanol (3 ml) and 1,4-dioxane (3 ml) at ambient temperature. Stirring was continued for 1.5 hours, and then water was added dropwise until a solution was achieved. After carefully acidifying with drops of concentrated hydrochloric acid, the solvents were evaporated in vacuo. The residue was partitioned between ethyl acetate and water, and the organic layer was separated and rewashed with water. The organic layer was dried (magnesium sulphate) and the solvents removed in vacuo. The residue was crystallised from a mixture of methanol and diethyl ether to give the title compound (105 mg).
