Reaction Steps

NH2OH (20 mL, 50% in water) was added to a stirred solution of tert-butyl 5-cyano-2-methylphenylcarbamate (34) (17.5 g, 75.3 mmol) in EtOH (200 mL) and the resulting solution was heated at 50° C. for 10 hours. The solvent was then evaporated and the product was titurated with EtOAc and hexane to obtain a white solid (Z)-tert-butyl 5-(N′-hydroxycarbamimidoyl)-2-methylphenylcarbamate (35) in a quantitative yield which was used without further purification. MS m/z 266.1 (M+1)+.
