Versuchsvorschrift

The resulting 1-(8-chloro-2-ethylimidazo[1,2-a]pyrazin-3-yl)-1-butanol was dissolved in N,N-dimethylformamide (2.2 mL), then iodoethane (0.079 mL, 0.99 mmol) and sodium hydride (65% in oil; 49 mg, 1.32 mmol) were added thereto under ice-cooling, and the mixture was stirred for 3 hours. Water was added to the reaction mixture, which was extracted with ethyl acetate and evaporated. The resulting residue was purified by silica gel column chromatography (ethyl acetate:n-hexane=1:3) to give the title compound (55 mg) as a colorless oil.
