To a solution of 1-(4-hydroxymethyl-phenyl)-ethanone (1 eq) in methanol is added O-(4-chloro-3-trifluoromethyl-benzyl)-hydroxylamine (1 eq) followed by the addition of acetic acid (0.05 eq). The mixture is stirred at room temperature for 5 hours. After concentrated, the residue is purified by column chromatography (30% EtOAc in hexane) to give 1-(4-hydroxymethyl-phenyl)-ethanone O-(4-chloro-3-trifluoromethyl-benzyl)-oxime as an oil [MS: (ES+) 358.1 (M+1)+].
