Procedure

The title compound was synthesized by mixing Compound 4 (25 mg, 0.10 mmol, benzenethiol (21 μl, 0.20 mmol), caesium carbonate (33 mg, 0.10 mmol) and [1,1′-Bis(diphenylphosphino)-ferrocene]dichloropalladium(II) (7 mg, 0.01 mmol) in DMF and heating at 170° C. for 20 minutes in a microwave reactor. The product was purified by HPLC (Yield=42%). 1H NMR (400 MHz, CH3OD) δ 8.97 (d, J=7.84 1H) 8.41 (d, J=5.56 Hz 1H) 7.55 (m, 3H) 7.50 (t, 1H) 7.40 (q, 1H) 7.36 (d, J=8.84 Hz 2H) 7.12 (d, J=7.36 Hz 1H) 2.11 (s, 3H). [M+H] calc'd for C19H15N3OS 334; found, 334.
