Procedure

5-Bromo-pyridine-2-carbonitrile (2.63 g, 13.7 mmol), sodium methanethiolate (1.44 g, 20.5 mmol), potassium carbonate (3.79 g, 27.4 mmol) in NMP (60 ml) were stirred in a sealed flask overnight. The mixture was partitioned between ethyl acetate and water. The organic phase was washed with water several times, brine and dried over sodium sulphate. The solvent was removed in vacuo to afford the title compound as a yellow solid (2.0 g, 99%).
