Versuchsvorschrift

To a solution of 4-cyclobutyl-5-(5-ethyl-1H-pyrazol-3-yl)-2-methylbenzoic acid (compound 445.3, 130 mg, 0.460 mmol, 1.00 equiv) in N,N-dimethylformamide (5 mL) were added 4-(Piperidin-4-yl)benzonitrile hydrochloride (1.5, 102 mg, 0.460 mmol, 1.00 equiv), EDCI (176 mg, 0.920 mmol, 2.00 equiv), and 4-dimethylaminopyridine (112 mg, 0.920 mmol, 2.00 equiv). The resulting solution was stirred for 2 h at 30° C., and then diluted with 40 mL of ethyl acetate. The mixture was washed with 3×40 mL of brine, dried (Na2SO4), and concentrated under reduced pressure. The crude product was purified by Prep-HPLC with the following conditions (1#-Pre-HPLC-001(SHIMADZU)): Column, SunFire Prep C18, 19*150 mm 5 um; mobile phase, water with 0.05% TFA and CH3CN (59.0% CH3CN up to 73.0% in 6 min, up to 100.0% in 7 min, down to 59.0% in 1 min); Detector, Waters 2489 254&220 nm. The fractions containing pure compound were combined and lyophilized to yield 150 mg (72%) of the title compound as a white solid. m/z (ES+) 453 (M+H)+.
