Procedure

TBTU (295 mg; 0.92 mmol) and N-methylmorpholine (253 μl; 232 mg; 2.3 mmol) were added to a solution of 6-(4-fluoro-3-methylphenyl)-5,6,7,8-tetrahydroimidazo[1,2-a]pyridine-2-carboxylic acid hydrochloride (210 mg; 0.68 mmol) in DMF (1 ml). The reaction mixture was stirred vigorously for 30 min at room temperature and then 1-(3-trifluoromethylphenyl)piperazine (173 μl; 212 mg; 0.92 mmol) was added. The reaction mixture was stirred for 4 h at room temperature and poured onto water. The precipitated solid was purified by column chromatography on silica gel (chloroform). Yield: 166 mg (50%)
