실험 절차
To a solution of (2S,3R,4R,5S,6R)-2-(4-chloro-3-(4-hydroxybenzyl)phenyl)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (intermediate D1) (30 mg, 0.08 mmol) in anhydrous DMF (1 mL) were added 2-cyclopropoxyethyl 4-methylbenzenesulfonate (intermediate BP) (20 mg, 0.08 mmol) and Cs2CO3 (52 mg, 0.16 mmol). The mixture was stirred at room temperature for 12 h. Then the reaction mixture was poured into water, extracted with EA, washed with brine, dried with anhydrous Na2SO4 and concentrated to an oil. The oil was purified by preparative HPLC to obtain compound BQ (11 mg) as a colorless oil. 1H NMR (CD3OD): δ 7.30 (m, 3H), 7.11 (d, J=8.8 Hz, 2H), 6.82 (d, J=8.8 Hz, 2H), 4.13 (m, 5H), 3.85 (m, 3H), 3.81 (m, 1H), 3.40 (m, 4H), 3.30 (m, 1H), 0.52 (m, 4H); MS ESI (m/z) 465 (M+H)+, calc. 464.
