실험 절차
N,N-Diphenylcarbamoylpyridinium hydrochloride (0.132 g.) was added to a stirred solution of 4-[5-(cyclopentyloxycarbonyl)amino-1-methylindol-3-ylmethyl]-3-methoxybenzoic acid (obtained as described in Example 9) (0.15 g.) and sodium hydroxide (0.35 ml. of 1M aqueous solution) in absolute ethanol (6 ml.), under an atomosphere of nitrogen. The mixture was stirred for 15 minutes, and was then partitioned between ethyl acetate (50 ml.) and water (30 ml.). The organic layer was washed successively with 1M hydrochloric acid (20 ml.) and saturated brine (20 ml.), then dried (MgSO4), and evaporated to give 4-[5-(cyclopentyloxycarbonyl)amino-1-methylindol-3-ylmethyl]-3-methoxybenzoic N,N-diphenylcarbamic anhydride, as a white foam. This foam was dissolved in N,N-dimethylformamide (DMF) (3 ml.), and added to a stirred solution of the sodium salt of benzenesulphonamide (0.19 g.) in DMF (6 ml.), under an atmosphere of nitrogen. The mixture was stirred for 1 hour and then poured into 1M hydrochloric acid (40 ml.). The acid mixture was extracted with ethyl acetate (2×30 ml.). The combined extracts were dried (MgSO4) and evaporated. The yellow oil obtained was purified by the following successive procedures:
