실험 절차

Add PyBOP (343 mg, 0.65 mmol) and triethylamine (0.21 mL, 1.50 mmol) to a stirred solution of 1-(6-(4-fluorophenyl)-4,5-dimethylpyridazin-3-yl)-N-methylpiperidin-4-amine (157 mg, 0.50 mmol) and 1-(4-methoxybenzyl)-3-(trifluoromethyl)-1H-pyrazole-4-carboxylic acid (165 mg, 0.55 mmol) in anhydrous DMF (2.5 mL). Stir the resulting mixture at ambient temperature under N2 overnight. Concentrate, add MeOH, filter solids, and concentrate the filtrate. Dilute the residue with MeOH, and pour onto an SCX column (Thermo Scientific, 10 g). Wash with MeOH, and then elute the product with 2 M NH3/MeOH. Concentrate and purify by flash silica gel chromatography using a gradient of 0 to 10% (10% 2 M NH3/MeOH in EtOAc) in hexanes to obtain the title compound as a white solid (170 mg, 43%). ES/MS m/z 597.0 (M+1).
