tert-Butyl N-[8-bromo-6-methyl-2-(methylsulfanyl)imidazo[1,2-a]pyridin-3-yl]carbamate (123 mg) was dissolved in N,N-dimethylformamide (10 mL), then sodium hydride (65% in oil; 15 mg) was added thereto under ice-cooling, and the mixture was stirred for 10 minutes. Iodopropane (67 mg) was added thereto under ice-cooling, and the mixture was stirred at room temperature for 1 hour. The reaction mixture was poured into water, which was extracted with ethyl acetate. The extracted organic layers were combined, dried over anhydrous magnesium sulfate and evaporated, to give the title compound (133 mg) as a brown oil.
