実験手順
To a stirred suspension of 250 mg (1.01 mmol) 6-amino-4-furan-2-yl-2-methanesulfinyl-nicotinonitrile in 10 ml DME was added 0.41 ml (4.04 mmol) 2-picolylamine and the mixture heated at 100° C. for 16 hours. The reaction mixture was then cooled to room temperature and partitioned between water and dichloromethane. The organic phase was dried over sodium sulfate and concentrated in vacuo. Chromatography (ethyl acetate) followed by trituration in ether afforded 100 mg (34%) 6-amino-4-furan-2-yl-2-[(pyridin-2-ylmethyl)-amino]-nicotinonitrile as an off-white crystalline solid. ES-MS m/e (%): 292 (M+H+, 100).
