Reaction Steps

80 mg (0.031 mmol) of (S)-N-(1-(4-(2-acetyl-1-methyl-1H-imidazol-4-yl)phenyl)-4-hydroxybutan-2-yl)-3-chloro-4-isopropoxybenzamide in 2 mL of pyridine was treated with 27.6 mg (0.033 mmol) of hydroxylamine methyl ether hydrochloride. The reaction was stirred overnight after which the solvents were evaporated and the residue purified via reverse phase HPLC (acetonitrile/water). 11.2 mg (70% yield) of 2 was obtained and characterized by LCMS and HNMR.
