Into a 50-mL round bottom flask, was placed 2-amino-5-(piperidin-1-yl)-N-(1-(3-(trifluoromethyl)phenyl)-1H-pyrazol-3-yl)benzamide 8d (100 mg, 0.23 mmol, 1.00 equiv) in tetrahydrofuran (5 mL), and N,N-diisopropylethylamine (60 mg, 0.47 mmol, 2.00 equiv). To this was added 3-(bromomethyl)benzoyl chloride (75 mg, 0.32 mmol, 1.39 equiv), in portions at 0° C. The resulting solution was stirred for 2.5 h at room temperature. The reaction progress was monitored by LCMS/TLC. The resulting mixture was concentrated under vacuum. The resulting solution was diluted with 10 mL of water, extracted with 3×10 mL of ethyl acetate, and the organic layers combined. The resulting mixture was washed with 3×10 mL of brine, dried over anhydrous sodium sulfate, and concentrated under vacuum. This resulted in 160 mg (88%) of product as a brown solid.
