Hydrogen Peroxide → 5-(Methylsulfinyl)-3-[4-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]pentane-nitrile

Participants

Reaction Steps

A solution of 5-(methylthio)-3-[4-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]-pentanenitrile prepared as in Example 90 (0.065 g, 0.00021 mol) and hydrogen peroxide (0.022 mL, 0.00023 mol) in ACN (1 mL, 0.02 mol) was stirred overnight. The reaction was concentrated and purified by HPLC to give 21 mg of a solid. The solid was triturated with MTBE (1 mL)/DCM (10 drops). The solid was filtered and washed to give 13 mg of a white solid (20% yield) which was dried rt to 50° C. for 2 h.
