Reaction Steps

A suspension of 6-chloro-4-nitroisobenzofuran-1(3H)-one (5 g, 23.5 mmol) and Pd/C (10%, 500 mg) in EtOAc (250 mL) was stirred at 25° C. under 1 atm of hydrogen for 12 hr. The mixture was filtered, and the cake was washed with EtOAc (100 mL×3). The filtrate was concentrated to give the title compound (3.87 g, yield 90%) as a white solid. LC-MS (ESI) m/z: 184 (M+1)+.
