Versuchsvorschrift

1-(Benzo[d][1,3]dioxol-5-yl)-N-(2-tert-butyl-1-(1,3-dihydroxypropan-2-yl)indolin-5-yl)cyclopropanecarboxamide (40.3 mg, 0.0711 mmol as the trifluoracetic acid salt) was dissolved in toluene (1 mL). To the resulting solution was added 2,3,5,6-tetrachlorocyclohexa-2,5-diene-1,4-dione (35 mg, 0.14 mmol). The resulting suspension was heated at 100 CC in an oil bath for 10 minutes. The crude product was then evaporated to dryness, dissolved in a 1 mL of NA-dimethylformamide and purified by purified by preparative HPLC using a gradient of 0-99% acetonitrile in water containing 0.05% trifluoroacetic acid to yield 1-(benzo[d][1,3]dioxol-5-yl)-N-(2-tert-butyl-1-(1,3-dihydroxypropan-2-yl)-1H-indol-5-yl)cyclopropanecarbox amide. ESI-MS m/z calc. 450.2, found 451.5 (M+1)+. Retention time of 1.59 minutes.
