Into a 50-mL round-bottom flask, was placed a solution of 5-(4-chloro-2-(hydroxymethyl)-1H-imidazol-5-yl)-2,4-dimethylbenzoic acid (compound 230.6, 180 mg, 0.64 mmol) in N,N-dimethylformamide (15 mL). 4-(3-fluoroazetidin-3-yl)benzonitrile hydrochloride (compound 43.4, 165 mg, 0.78 mmol), EDC.HCl (245 mg, 1.28 mmol) and 4-dimethylaminopyridine (310 mg, 2.54 mmol) were added to the reaction. The reaction mixture was stirred overnight at 25° C. The reaction was then quenched with 5 mL of water. The reaction mixture was extracted with 3×10 mL of ethyl acetate and the organic layers combined. The resulting mixture was washed with 5×10 mL of brine. The resulting mixture was concentrated under reduced pressure. The crude product (200 mg) was purified by Prep-HPLC with the following conditions (1#-Pre-HPLC-001 (SHIMADZU)): Column, SunFire Prep C18 OBD Column, 5 μm, 19*150 mm; mobile phase, WATER WITH 0.05% TFA and ACN (26.0% ACN up to 39.0% in 10 min, up to 100.0% in 2 min, down to 26.0% in 1 min); Detector, Waters 2489, 254 and 220 nm. This resulted in 84 mg (30%) of the title compound as a white solid. m/z (ES+) 439 (M+H)+.
