Reaction Conditions

Reaction Steps

3-methyl-1,2-benzisoxazol-4-ol (Intermediate 10, 137 mg) was stirred with 1-fluoro-4-nitrobenzene (130 mg, 0.92 mmol) in DMF (3.0 ml) with potassium carbonate (381 mg, 2.8 mmol). The reaction mixture was heated at 110° C. for 1 hour under microwave irradiation After removal of the volatiles, the residue was purified by silica gel chromatography eluting with CyHex/EtOAc (100%/0% to 0%/100%) to afford the title compound (100 mg).
