Reaction Steps

2-Aminoethanol (57 μL, 0.944 mmol) was added to a solution of ethanol (0.5 mL) containing (4Z)-2-(4-{2-[4-(dimethylamino)phenyl]ethoxy}phenyl)-4-[4-(trifluoromethoxy)benzylidene]-1,3-oxazol-5(4H)-one (234 mg, 0.471 mmol) prepared in Example 23 (23c). The mixture was stirred at 60° C. for 2.5 hours, and then the solvent was evaporated. The resulting residue was purified by silica gel column chromatography (ethyl acetate:methanol, 50:1, v/v) to give 167 mg of the title compound (white amorphous solid, yield: 64%).
