Water → N-[2-[[6-[(3S)-3-methylmorpholin-4-yl]-2-[4-[(1-methylpyrazol-4-yl)methylcarbamoylamino]phenyl]pyrimidin-4-yl]methylsulfonyl]ethyl]acetamide

Reaktionsschritte

meta-Chloroperbenzoic acid (156 mg, 0.90 mmol) dissolved in Dioxane (2 mL), and sodium permanganate monohydrate (192 mg, 1.20 mmol) dissolved in water (1 mL) were added dropwise to N-[2-[[6-[(3S)-3-methylmorpholin-4-yl]-2-[4-[(1-methylpyrazol-4-yl)methylcarbamoylamino]phenyl]pyrimidin-4-yl]methylsulfanyl]ethyl]acetamide (162 mg, 0.30 mmol) in dioxane (6 mL) and water (2 mL) at RT under nitrogen. The resulting solution was stirred at RT for 1 hour. The crude product was purified by ion exchange chromatography, using an SCX column. The desired product was eluted from the column using 7M ammonia in methanol and pure fractions were evaporated to dryness. The crude product was purified by preparative HPLC using decreasingly polar mixtures of water (containing 1% NH3) and MeCN as eluents, to give the desired material as a white solid (61 mg).
