Reaction Steps

Add 2M trimethylaluminum in toluene (1.94 mL, 3.88 mmol) to a solution of morpholine (0.34 g, 3.88 mmol) in dichloromethane (10 mL). Stir for 10 min and add a solution of (6-bromo-imidazo[1,2-a]pyridin-2-yl)-acetic acid ethyl ester (1.1 g, 3.88 mmol) in dichloromethane (12 mL). Heat at 40° C. for 1 h, carefully dilute with saturated aqueous ammonium chloride and extract into dichloromethane. Concentration followed by filtration gives the titled compound (0.55 g, 43%) as a white solid.
