Procedure
To a stirred suspension of 1.00 g (4.62 mmol) 2-amino-4-chloro-6-methanesulfinyl-pyrimidine-5-carbonitrile in 10 ml DME were added 642 mg (4.62 mmol) 2-mercapto-ethylpyridine and 1.05 ml (6.92 mmol) DBU and stirring continued for 1 hour at room temperature. 50 ml water was then added and the resulting crystals collected by filtration and washed with ether. Chromatography (ethyl acetate/hexane 111 then ethyl acetate) followed by trituration in ether afforded 300 mg (22%) 2-amino-4-chloro-6-(2-pyridin-2-yl-ethylsulfanyl)-pyrimidine-5-carbonitrile as a white crystalline solid. ES-MS m/e (%): 294 (M{37Cl}+H+, 30), 292 (M{35Cl}+H+, 100).
