Procedure

A mixture of N-[6-(3-aminophenoxy)imidazo[1,2-a]pyridin-2-yl]cyclopropanecarboxamide (18.6 mg, 0.060 mmol), 3-phenylprop-2-ynic acid (13.1 mg, 0.090 mmol), HATU (48.7 mg, 0.128 mmol), N,N-diisopropylethylamine (35.1 μL, 0.205 mmol) and pyridine (1.5 mL) was stirred at 80° C. for 13 hr. The reaction mixture was diluted with aqueous sodium hydrogen carbonate solution and extracted with ethyl acetate. The organic layer was concentrated, and the residue was purified by preparative HPLC to give the title compound (4.6 mg, 18%).
