HCID 23659910, compound → 1-{[2-tert-butyl-1-(tetrahydro-2H-pyran-4-ylmethyl)-1H-benzimidazol-5-yl]sulfonyl}-1H-pyrazole-4-carboxylic acid

Participants

Reaction Steps

Oxone (596 mg, 0.97 mmol) was added to a solution of 1-{[2-tert-butyl-1-(tetrahydro-2H-pyran-4-ylmethyl)-1H-benzimidazol-5-yl]sulfonyl}-1H-pyrazole-4-carbaldehyde (380 mg, 0.88 mmol) (see example 23 for preparation) in DMF (15 mL). The resulting mixture was stirred overnight at room temperature and the solvent was concentrated. The residue was dissolved in DCM, washed with 10% HCl solution and dried over anhydrous Na2SO4. The solvent was concentrated to provide the title compound as white solid Yield: 330 mg (74%); MS (ESI) (M+H)+=447.09.
