Sodium sulfate decahydrate → HCID 23157205, compound

Participants

Reaction Steps

To a solution (40 mL) of methyl 6-(benzyloxy)-4′-(2-ethoxyethoxy)biphenyl-3-carboxylate (2.0 g, 4.92 mmol) in anhydrous tetrahydrofuran was added lithium aluminum hydride (0.19 g, 5.01 mmol) under ice-cooling, and the mixture was stirred at room temperature for 3 hr. The reaction solution was ice-cooled, and sodium sulfate decahydrate (3.0 g, 5.74 mmol) was added. The mixture was stirred at room temperature for 1 hr. The precipitated insoluble material was filtered off through celite, and the filtrate was concentrated under reduced pressure. The obtained residue was subjected to silica gel column chromatography (ethyl acetate:hexane=1:2-1:1), and the obtained crystals were recrystallized from ethyl acetate-hexane to give the title compound (1.7 g, yield 91%) as colorless needle crystals.
