反応手順
A solution of 5-[2-(methylsulfonyloxy)etylthio]imidazo[1,2-a]pyridine (2.18 g, 8 mmoles), triethylamine (2.24 ml, 16 mmoles) and a 40% methylamine-methanol solution (20 ml) in chloroform (20 ml) was heated at reflux for 3 hours. The reaction mixture was washed with 3N NaOH and dried over anhydrous magnesium sulfate. After the solvent was distilled off, the residue was purified by column chromatography [eluent: methanol/chloroform (1:10)] to obtain 781 mg of the desired product (47.1%, light brown oily product).
