4-Chloronicotinaldehyde [prepared according to D. Albanese, M. Penso, M. Zenoni, Synthesis 1999, 1294-1296] (500 mg, 3.5 mmol), 4-methylsulfanyl-benzenethiol (606 mg, 3.88 mmol) potassium carbonate (586 mg, 4.24 mmol) and DMF (7 mL) were combined, the mixture was heated together at 50° C. for 1.5 h and then stirred at room temperature overnight. The solvent was removed in vacuo and the residue was partitioned between EtOAc (100 mL) and 10% aqueous K2CO3 (100 mL). The organic layer was dried (MgSO4) and evaporated to give the title compound (1.05 g) as a yellow oil. The 1H NMR spectrum showed the material to be of sufficient purity (90-95%) to be used without further purification; δH (CDCl3, 400 MHz) 2.54 (3H, s), 6.69 (1H, d), 7.35 (2H, d), 7.4 (2H, d), 8.35 (1H, d), 8.87 (1H, s), 10.24 (1H, s); MS m/z (TS+) 262 (MH+).
