Reaction Conditions

Reaction Steps

An oven-dried round bottom flask was charged with 60.0 mg (0.152 mmol) of the product of Example 36 and Cs2CO3 (250.0 mg, 0.767 mmol), toluene (1.0 mL) and 4-fluorobenzene thiol (97.5 mg, 0.761 mmol) were added sequentially. The reaction was heated to 100° C. for 23 hours and then allowed to cool to room temperature at which point the reaction was filtered and concentrated. The residue was purified by preparative thin layer chromatography (20 cm×20 cm, 1000 μm, silica gel) eluting with 10:90 EtOAc-hexane affording a white solid). MS (electrospray) m/e 487 MH+.
