p-Toluenesulfonic acid → HCID 71138308, compound

Participants

Reaction Steps

To a solution of 2-(4-(1H-1,2,4-triazol-1-yl)phenyl)-4-(3,5-dichlorophenyl)-5,5,5-trifluoropentan-2-ol (100 mg, 0.233 mmol) in toluene was added a catalytic amount of p-toluenesulfonic acid and the water was removed by azeotropic distillation over the course of 12 h. The reaction mixture was cooled to room temperature and dissolved in EtOAc. The solution was washed with sat aqueous NaHCO3 solution and brine, dried over Na2SO4 and concentrated under reduced pressure. Purification by column chromatography (SiO2, 100-200 mesh; 20%-25% EtOAc in petroleum ether) afforded the title compound as a solid (30 mg, 31%).
