Versuchsvorschrift

A mixture of 1-benzenesulfonyl-2-[2-cyclopentyl-1-(2,3-dihydro-benzo[1,4]dioxin-6-yl)-vinyl]-1H-pyrrolo[2,3-b]pyridine (130 mg, 0.27 mmol) in ethanol (6 mL) and tetrahydrofuran (3 mL) and an aqueous sodium hydroxide solution (10%, 1 mL) was stirred at 40° C. for 48 h. The mixture was diluted with ethyl acetate (100 mL), washed with water, dried over anhydrous sodium sulfate and then concentrated in vacuo to afford 2-[2-cyclopentyl-1-(2,3-dihydro-benzo[1,4]dioxin-6-yl)-vinyl]-1H-pyrrolo[2,3-b]pyridine (80 mg, 87%) as a white solid: LC/MS m/e calcd for C22H22N2O2 [M+H]+ 347.43, observed 347.1.

Aufarbeitung
