m-Chloroperbenzoic acid → 1-(4'-(Cyclopropylmethyl)-2-(methylsulfinyl)-4,5'-bipyrimidin-2'-ylamino)-2-methylpropan-2-ol

Participants

Reaction Steps

To a solution of 1-(4′-(Cyclopropylmethyl)-2-(methylthio)-4,5′-bipyrimidin-2′-ylamino)-2-methylpropan-2-ol (90 mg, 0.261 mmol) in DCM (521 μl), mCPBA (70.6 mg, 0.287 mmol) was added in portions, and the reaction mixture was stirred at rt for 1 h. The crude product was purified by a Biotage silica gel chromatography [10 g SNAP column, 100% DCM to 12% MeOH/DCM] to obtain the desired product as a yellow solid (38 mg, 40% yield). MS (ES+): m/z=362.2 (100) [MH+]. HPLC: tR=0.90 min over 3 min. Purity: 100% [HPLC (LC/MS) at 220 nm].
