Procedure

To a solution of methyl (4-cyanophenyl)acetate (4.00 g, 27.8 mmol) in MeOH (20 mL), hydroxylamine hydrochloride (3.17 g, 45.7 mmol) and NaHCO3 (3.84 g, 45.7 mmol) is added. The suspension is stirred at 60° C. for 18 h before it is filtered and the filtrate is concentrated. The residue is dissolved in DCM, washed with water followed by brine, dried over MgSO4, filtered, concentrated and dried to give methyl [4-(N-hydroxycarbamimidoyl)-phenyl]-acetate (3.67 g) as a colourless oil; LC-MS: tR=0.50 min, [M+1]+=209.05.
