Reaction Steps

Iodoxybenzoic acid (830 mg, 2.96 mmol) was added to a solution of trans-[4-(4-benzo-triazol-1-yl-pyrimidin-2-ylamino)-cyclohexyl]-methanol (640 mg, 1.97 mmol) in DMSO (10 mL) and the resulting mixture was stirred at RT for 23 hours. An additional aliquot of o-iodoxy-benzoic acid (830 mg, 2.96 mmol) was then added. After a few hours, the reaction was stopped. Water was added and the resulting mixture was stirred for 20 minutes, the solid formed was filtered and the filtrate was extracted 3 times with EtOAc. The combined organic extracts were washed once with water, dried over Na2SO4 and filtered; the solvent was evaporated under reduced pressure. The white solid formed was washed several times with EtOAc and it was combined with the previous obtained solid to give 789 mg of crude residue. This crude material was purified via flash chromatography (heptane/EtOAc, with a gradient from 20% to 50% of EtOAc) to give 452 mg (70% yield) of 4-(4-benzotriazol-1-yl-pyrimidin-2-ylamino)-cyclo-hexanecarbaldehyde.
