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 ).
