Acetic Acid → [(2R,3R,4S,5R,6R)-3,4,5-triacetoxy-6-[3-[(4-bromophenyl)methyl]-4-methyl-indolin-1-yl]tetrahydropyran-2-yl]methyl acetate

Participants

Reaction Steps

Add [(2R,4S,5R,6S)-3,4,5,6-tetraacetoxytetrahydropyran-2-yl]methyl acetate (10.6 mmol) and 3-[(4-bromophenyl)methyl]-4-methyl-indoline (10.6 mmol) to a solution of acetic acid (69.8 mmol) in methanol (80 mL). Stir at room temperature overnight. Filter the reaction mixture through a glass frit and wash the filter cake with methanol (2×10 mL). Dry the filter cake under vacuum to yield the title compound (2.3g, 3.6 mmol): MS (m/z): 632 (M+H).
