Procedure

To (2S,3R,4R,5S,6R)-2-(4-chloro-3-(4-hydroxybenzyl)phenyl)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (intermediate D1) (200 mg) in anhydrous DMF were added 2-(2,2,2-trifluoroethoxy)ethyl 4-methylbenzenesulfonate (intermediate BS) (1.5 eq) and Cs2CO3 (2 eq). The mixture was stirred at room temperature for 12 h, after which LC-MS showed the reaction was complete. The reaction mixture was poured into water, extracted with EA, washed with water and brine, and then dried with anhydrous Na2SO4 and concentrated to an oil. The oil was purified by preparative-HPLC to obtain compound BT (117 mg). 1H NMR (CD3OD, 400 MHz): δ 7.32 (m, 3H), 7.11 (d, J=8.8 Hz, 2H), 6.86 (d, J=8.8 Hz, 2H), 4.62 (s, 2H), 4.08˜4.12 (m, 3H), 4.02˜4.05 (m, 3H), 4.00˜3.94 (m, 2H), 3.90˜3.87 (m, 1H), 3.72˜3.68 (m, 1H), 3.46˜3.39 (m, 3H), 3.30˜3.27 (m, 1H); MS ESI (m/z) 507 (M+H)+, calc. 506.
