実験手順

2-(7-Aza-1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (HATU) (49 mg, 0.129 mmol) was added to a suspension of 1-(tert-butoxycarbonyI)-5-phenylpiperidine-3-carboxylic acid (36 mg, 0.117 mmol) in DMF (0.5 mL) and was stirred at room temperature for 15 minutes. A solution of 3-(pyridin-4-yl)-1-trityl-1H-indazol-5-amine (0.117 mmol) in DMF (0 5 mL) was added to the reaction and followed by diisopropyl ethyl amine (DIEA) (0.1 mL). The mixture was stirred at room temperature for an additional 30 minutes. The reaction was quenched with water (5 mL) and extracted with ethyl acetate (3×10 mL). The extracts were combined, dried using anhydrous sodium sulfate, filtered, and concentrated in vacuo. The crude product was progressed to the next step without purification.
