Reaction Conditions

Reaction Steps

To a solution of 2-amino-N-[1-(4-chloro-phenyl)-ethyl]-benzamide (115 mg, 0.42 mmol) in THF (30 mL) is added trichloromethyl chloroformate (50 mg, 0.25 mmol). The mixture is stirred at 90° C. for 4 hours. The reaction mixture is allowed to cool to room temperature, neutralizes with 1M NaOH aq. The reaction mixture is extracted with EtOAc (50 mL×3). The organic layer is dried over sodium sulfate and is concentrated to give the desired 3-[1-(4-chloro-phenyl)-ethyl]-1H-quinazoline-2,4-dione (125 mg, 99%).
