To a stirred suspension of 1.00 g (4.08 mmol) 2-amino-4-bromo-6-methylsulfanyl-pyrimidine-5-carbonitrile in 10 ml DME were added 0.33 ml (4.08 mmol) 2-(hydroxymethyl)pyridine and 0.62 ml (4.08 mmol) DBU and stirring continued for 16 hours at room temperature. 50 ml water was then added and the resulting crystals collected by filtration. Chromatography (ethyl acetate) followed by trituration in ether afforded 180 mg (16%) 2-amino-4-methylsulfanyl-6-(pyridin-2-ylmethoxy)-pyrimidine-5-carbonitrile as a light yellow crystalline solid. EI-MS m/e (%): 273 (M+, 100), 258 (89), 108 (63), 92 (95), 65 (70), 39 (36).
