실험 절차

To a solution of the (R)-2-hydroxy-3-(7-methyl-2-((2-(trimethylsilyl)ethoxy)methyl)-2H-indazol-5-yl)propanoic acid (610 mg, 1.74 mmol), diisopropylethylamine (0.61 mL, 3.48 mmol), and 4-piperidinopiperidine (585.76 mg, 2.0 equiv) in dimethylformamide (20 mL) and dichloromethane (20 mL) at 0° C. was added PyBOP® (951 mg, 1.83 mmol). The reaction was stirred at 0° C. for 2 h. The reaction was concentrated, diluted with ethyl acetate, washed with water, then brine, dried over magnesium sulfate, and concentrated. The product was purified by column chromatography (4:96:1 methanol/dichloromethane/triethylamine) to give 795 mg (91%). Mass spec.: 501.40 (MH)+.
