A solution of 4-cyclobutyl-5-(5-ethoxy-4H-1,2,4-triazol-3-yl)-2-methylbenzoic acid (compound 219.9, 40 mg, 0.13 mmol), DIEA (0.07 ml, 0.39 mmol), HOBT (34 mg, 0.19 mmol, with 20% water), EDCI (38 mg, 0.19 mmol), and 4-(piperidin-4-yl)benzonitrile hydrochloride (compound 1.5, 36 mg, 0.16 mmol) in N,N-dimethylformamide (3 mL) was stirred overnight at room temperature. The reaction mixture was then diluted with 50 mL of ethyl acetate and washed with 2×20 mL of brine. The mixture was dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was applied onto a silica gel prep-TLC plate and developed using ethyl acetate/hexanes (1:1) to yield 0.1 g (68%) of the title compound as a white solid. m/z (ES+) 470 (M+H)+.
