The mixture of 2,4-dimethyl-5-(5-methyl-2-(tetrahydro-2H-pyran-4-yl)-1H-imidazol-4-yl)benzoic acid (compound 164.2, 157 mg, 0.5 mmol), 4-(azetidin-3-yl)benzonitrile hydrochloride (compound 5.2, 126 mg, 0.65 mmol), EDCI (143 mg, 0.75 mmol), HOBt (93 mg, 0.55 mmol) and DIEA (345 μL, 2.00 mmol) in DMF (4 mL) was stirred at room temperature for 16 hours. The reaction was diluted with water and extracted with EtOAc (30 mL). The organic phase was washed with saturated NaHCO3 (10 mL), brine (3×20 mL), dried over MgSO4 and concentrated under reduced pressure. The residue was purified by preparative TLC with 5% methanol in dichloromethane and lyophilized to give 95 mg (42%) of the title compound as a white solid. m/z (ES+) 455 (M+H)+.
