Into a 100-mL round-bottom flask, was placed a solution of 5-(2-(cyanomethyl)-4-methyl-1H-imidazol-5-yl)-2,4-dimethylbenzoic acid (compound 222.6, 190 mg, 0.71 mmol) and HBTU (538 mg, 1.42 mmol) in NA-dimethylformamide (3 mL). To the above were added a solution of 4-(3-fluoroazetidin-3-yl)benzonitrile hydrochloride (compound 43.4, 160 mg, 0.75 mmol) and triethylamine (197 μL, 1.42 mmol) in N,N-dimethylformamide (3 mL) dropwise. The reaction mixture was stirred for 1 h at room temperature. The crude product (150 mg) was purified by Prep-HPLC with the following conditions (1#-Pre-HPLC-001(SHIMADZU)): Column, XBridge Prep C18 OBD Column, 5 μm, 19*150 mm; mobile phase, Water with 50 mmol NH4HCO3 and acetonitrile (30% acetonitrile up to 44% in 7 min, hold 44% in 1 min, up to 100% in 1 min, down to 30% in 1 min); Detector, Waters 2489, 254 and 220 nm. This resulted in 45.9 mg (15%) of the title compound as a white solid. m/z (ES+) 428 (M+H)+.
