Reaction Steps

Subsequently, 4-imidazo[1,2-a]pyridin-2-ylbenzaldehyde g) was dissolved in tetrahydrofuran (100 mL), followed by stirring under ice cooling. Methyl magnesium bromide (3.0M diethyl ether solution, 4.4 mL) was added dropwise to the reaction mixture, followed by stirring at room temperature for 1 hour. Saturated aqueous ammonium chloride solution (5 mL) was added dropwise to the reaction mixture, followed by stirring at room temperature for 1 hour. Water was added to the reaction mixture, and the mixture was extracted with chloroform, followed by drying over magnesium sulfate. The solvent was evaporated, and the solid was recovered through filtration by use of dichloromethane-methanol (30:1) mixture. The filtrate was concentrated under reduced pressure, and the residue was subjected to flash chromatography. Fractions eluted by dichloromethane-methanol (30:1) were concentrated under reduced pressure, and the solid was recovered through filtration by use of diethyl ether. Through the above procedure, 1-(4-imidazo[1,2-a]pyridin-2-ylphenyl)-1-ethanol (2.43 g) was yielded.
