実験手順

To a solution of 3-(hydroxymethyl)-imidazo[1,2-a]pyridine-6-carbonitrile (7-2) (346 mg, 2 mmol) in 20 mL of THF was added sodium hydride (240 mg, 60% in oil) at 0° C. The reaction mixture was stirred at 0° C. for 1 h, then methyl iodide (615 mg, 4.3 mmol) was added. The reaction was stirred at room temperature overnight. The mixture was treated with aqueous Na2CO3, then concentrated. The residue was diluted with water and extracted with EtOAc. The combined organics were dried over Na2SO4 and concentrated to afford the title compound (300 mg). MS (m/z): 188.0 (M+H)+
