실험 절차

To a solution of 2-chloro-5-(2-chloro-5-((2S,3S,4R,5R,6R)-3,4,5-tris(benzyloxy)-6-(benzyloxymethyl)-tetrahydro-2H-pyran-2-yl)benzyl)-1,3,4-thiadiazole (419 mg, 0.55 mmol) from Step 2 in tetrahydrofuran (10 mL) was added sodium methanethiolate (77 mg, 1.1 mmol). The resulting mixture was stirred at ambient temperature overnight. After cooling to 0° C., the reaction was quenched with hydrochloric acid (1.0 M) and diluted with ethyl acetate and water. The organic layer was separated and the aqueous layer was extracted with ethyl acetate. The combined organic layers were washed with brine, dried over magnesium sulfate, filtered and concentrated in vacuo. The residue was purified on Biotage® purification apparatus (silica gel, 10 to 60% ethyl acetate in hexanes) to yield the title compound (331 mg, 0.42 mmol, 77%) as a yellow oil. MH+ 779.
