実験手順

A well homogenised mixture of the Compound of Example 3 (19 mg, 0.89 mmol) and 3-fluoro-4-nitrotoluene (20.2 mg, 0.13 mmol) was stirred at 120° C. for 0.5 h. The reaction crude was purified by flash chromatography (EtOAc—Petroleum Ether gradient from 2:8 to 3:7) affording the title product (18 mg).
