Procedure

A mixture of (3-(piperazin-1-yl)azetidin-1-yl)(6-(trifluoromethyl)benzo[b]thiophen-2-yl)methanone (0.14 mmol, 50 mg), 2-bromopyrimidine (0.23 mmol, 37 mg), and K2CO3 (0.34 mmol, 47 mg) in THF (3 mL) and water (1.5 mL) was refluxed for 8 h. Following workup and extraction, the residue was purified by flash column chromatography (silica gel, 3% methanol/CH2Cl2) to yield (3-(4-(pyrimidin-2-yl)piperazin-1-yl)azetidin-1-yl)(6-(trifluoromethyl)benzo[b]thiophen-2-yl)methanone as a white solid.
