Benzenesulfonic acid, 4-methyl-, compd. with pyridine (1:1) → HCID 90418188, compound

Participants

Reaction Steps

Into a 250-mL round-bottom flask, was placed 2-[[3-(4-chlorophenyl)-5-fluorothiophen-2-yl]methoxy]oxane (1.6 g, 4.90 mmol, 1.00 equiv), ethanol (100 mL), PPTS (120 mg, 0.48 mmol, 0.10 equiv). The resulting solution was stirred overnight at room temperature. The resulting mixture was concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:2). This resulted in 0.7 g (59%) of [3-(4-chlorophenyl)-5-fluorothiophen-2-yl]methanol as yellow oil.
