Isopropanol → HCID 178504602, Verbindung

N-(cis-4-Hydroxymethyl-cyclohexyl)-5-fluoro-2-(3-methylsulfanyl-phenoxy)-nicotinamide (120 mg, 0.307 mmol) was dissolved in a solvent mixture of isopropyl alcohol (4 ml), tetrahydrofuran (1 ml) and water (0.5 ml) and oxone™ (132 mg, 0.215 mmol) was added. The reaction was stirred at room temperature for 2 h. The reaction mixture was diluted with water (5 ml) and extracted with dichloromethane (3×10 ml). The combined organic extracts were dried over MgSO4 and the solvent was removed under reduced pressure. The residue was purified by flash column chromatography on silica gel eluting with dichloromethane:methanol (98:2 increasing to 97:3, by volume). The resulting foam was triturated with diethylether (5 ml) to give the product (108 mg) as a white solid.
