Reaction Steps

[step 1] Commercially available 3-methoxypyridin-2-amine (1.0 g, 8.06 mmol) was dissolved in ethanol (8.1 mL), 1-bromo-3-methylbutan-2-one (Organic Syntheses, 1976, vol. 55, p 24; 1.46 g, 8.86 mmol) was added, and the mixture was stirred at 110° C. for 13 hr. To the mixture was added saturated aqueous sodium hydrogen carbonate, and the mixture was extracted 3 times with chloroform. The combined organic layers were dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=100/0 v/v-30/70 v/v) to give 2-isopropyl-8-methoxyimidazo[1,2-a]pyridine (746 mg, 49%).
