実験手順
To a stirred solution of 493 mg (1.58 mmol) 2-amino-4-(5-bromo-furan-2-yl)-6-methylsulfanyl-pyrimidine-5-carbonitrile in 10 ml DME was added 2.1 ml (11,3 mmol) sodium methylate solution (5.4M in methanol) and the mixture heated at 50° C. for 1 h. The reaction mixture was then poured into 100 ml ice-water and the resulting precipitate collected by filtration and washed with water. Chromatography (ethyl acetate/hexane 1/1) afforded 363 mg (87%) 2-amino-4-(5-methoxy-furan-2-yl)-6-methylsulfanyl-pyrimidine-5-carbonitrile as a light yellow crystalline solid. EI-MS m/e (%): 262 (M+, 100).
