    By condensation of ethyl indolin-3-acetate (4) and 2,3,5-tri-O-benzoylribofuranosyl-1-acetate (5), ethyl 1-(2,3,5-tri-O-benzoyl-β-D-ribofuranosyl)indolin-3-acetate (6) was obtained in good yield. The indoline nucleoside 6 was aromatized to ethyl 1-(2,3,5-tri-O-benzoyl-β-D-ribofuranosyl)indol-3-acetate (7) with DDQ. The treatment of the indole nucleoside with barium hydroxide and methanol gave the methyl ester 8, which was further treated in water to give the desired 1-(β-D-ribofuranosyl)indol-3-acetic acid (9).
