Good point about imidazole. I wanted to discuss the choice of deprotection/clean-up method. Along with an aromatic ring our product will have four free hydroxyl groups (being an aromatic glucoside), making it fairly polar. The technique in the 2007 Organic Letters paper (10.1021/ol063113h) does not use an aqueous work-up. Four of the entries in their table are glycosides based upon monosaccharides. I don't have a strong opinion on whether or not this is a better approach versus versus the ones we have already mentioned.
"General workup procedure for removal of TBAF residue (Table 1, entry 1): A 10 mL flask containing a stirring bar was charged with substrate
(110 mg, 0.169 mmol). TBAF (1.0 M in THF, 1.35 mL, 1.35 mmol) was added via syringe. After the solution was stirred at room temperature for 4
h (no SM nor partially deprotected intermediate detected by TLC), CaCO3 (280 mg), DOWEX 50WX8-400. (840 mg, used as supplied), and MeOH
(2.0 mL) were added. The suspension was stirred at room temperature for 1 h. All insoluble materials were removed by filtration through a pad of Celite, and the filter cake was washed with MeOH thoroughly. The combined filtrates were evaporated to dryness under reduced pressure to give the crude product (36.3 mg, 111%) as a white solid. 1H NMR spectra of the crude product showed that 99.3% of tetrabutylammonium salt was removed by these operations."
