p-Toluenesulfonic acid monohydrate → HCID 58755286, compound

Participants

Reaction Steps

A solution of methyl (6-{[2′-methyl-4′-(tetrahydro-2H-pyran-2-yloxy)biphenyl-3-yl]methoxy}-2,3-dihydro-1-benzofuran-3-yl)acetate (4.49 g, 9.19 mmol) and p-toluenesulfonic acid monohydrate (0.175 g, 0.919 mmol) in methanol (50 mL) was stirred at room temperature for 30 hr. The reaction solvent was evaporated under reduced pressure, and the residue was diluted with ethyl acetate, washed with saturated brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (20%-60% ethyl acetate/hexane) to give the title compound (3.21 g, yield 86%) as a colorless viscous oil.
