Reaction Steps

A mixture of 2,6-difluoro-N-[3-(5-hydroxymethyl-1H-benzimidazol-2-yl)-1H-pyrazol-4-yl]-benzamide (800 mg, 2.17 mmol) and MnO2 (5.00 g, 57.5 mmol) in CH2Cl2/MeOH (10:1, 110 ml) was stirred at ambient temperature for 5 days. The mixture was filtered through a plug of Celite washing with MeOH and the filtrate reduced in vacuo to give 2,6-difluoro-N-[3-(5-formyl-1H-benzimidazol-2-yl)-1H-pyrazol-4-yl]-benzamide (380 mg, 48%) as a yellow solid. (LC/MS: Rt 3.41, [M+H]+ 368.04).
