p-Toluenesulfonic acid monohydrate → HCID 178462393, compound

Participants

Reaction Steps

In the same manner as that described in Example 3(3) a reaction was carried out using 4′-chloro-4-formylbenzanilide (300 mg, 1.2 mmol), (2R,3R)-2-(2,4-difluorophenyl)-3-[[1-(hydroxymethyl)-2-hydroxyethyl]thio]-1-(1H-1,2,4-triazol-1-yl)-2-butanol (359 mg, 1.0 mmol) and p-toluenesulfonic acid monohydrate (342 mg, 1.8 mmol) and the reaction mixture was treated according to a similar procedure to that described in Example 3(3) to give the trans isomer of the title compound (290 mg, yield 48%) as a colorless solid and the cis isomer (82 mg, yield 14%) as a colorless oil. The trans isomer was recrystallized from ethyl acetate-hexane to give white powdery crystals.
