실험 절차

To a stirred solution of 3-[5-Amino-4-(3-methoxybenzoyl)-pyrazol-1-yl]-4-methylbenzoic acid C (50 mg, 0.14 mmol, 1.0 eq) in 10 mL of DMF was added EDCI (41 mg 0.21 mmol, 1.5 eq), HOBt (29 mg, 1.5 mmol, 2.0 eq), and diisopropylethylamine (55 mg, 0.43 mmol, 3.0 eq) and the solution was stirred for 15 minutes at room temperature when methylamine hydrochloride (13 mg, 0.19 mmol, 1.5 eq) was added and the reation stirred for 1 hour. The mixture was diluted with EtOAc (300 mL) and washed with water (2×25 mL) and brine (25 mL), dried (Na2SO4) and concentrated. The product was purified by flash chromatography on silica gel to provide the product to provide the product (15 mg, 32%) as a brown solid: HPLC (4 minute 10-90 gradient) tR1.97 min; MS m/z 365.2 [M+H]+.
