실험 절차

5-Amino-1-(5-carboxy-2-methyl-phenyl)-1H-pyrazole-3-carboxylic acid ethyl ester (46 mg, 0.159 mmol) and O-(7-azabenzotriazol-1-yl)-N,N,N′N′-tetramethyluronium hexafluorophosphate (HATU) (67 mg, 0.175 mmol) were combined in DMF (500 μL) and stirred for 5 min at room temperature N-(3-amino-5-tert-butyl-2-methoxy-phenyl)-methanesulfonamide (48 mg, 0.175 mmol) was added to the reaction mixture followed by i-Pr2NEt (83 μL, 0.477 mmol). The solution was stirred at room temperature for 48 h then poured onto saturated NaHCO3. The aqueous layer was extracted with CH2Cl2 and the combined extracts were dried over Na2SO4, filtered, and concentrated. Purification by semi-prep HPLC provided the title compound (41 mg, 48%) as a yellow solid (TFA salt): mp 104-111° C. (dec.); ESI MS m/z 544 [C26H33N5O6S+H]+; HPLC>98%, tR=20.79 min.
