Reaction Steps

To a stirred solution of tert-butyl (2-cyclohexylethyl){6-[({[(1-methyl-1H-tetrazol-5-yl)(phenyl)methylene]amino}oxy)methyl]pyridin-2-yl}carbamate (0.252 g, 0.413 mmol, 1 eq.) in 5 ml of dry DCM, was added TFA (1.41 g, 12.39 mmol, 30 eq.) in one portion. The reaction was refluxed for 5 hrs. Then the solvent and excess TFA were evaporated. The residue was neutralised with TEA and purified by chromatography on silica gel to give N-(2-cyclohexylethyl)-6-[({[(1-methyl-1H-tetrazol-5-yl)(phenyl)methylene]amino}oxy)methyl]pyridin-2-amine (0.138 g, 76% yield) as a viscous oil.
