실험 절차

5-(2,4-Difluorophenoxy)-1-isobutyl-1H-indazole-6-carboxylic acid (17d; prepared according to Example 110) (25.0 g, 72.2 mmol), EDCI (18.0 g, 93.8 mmol), and 1-hydroxypyrrolidine-2,5-dione (9.97 g, 86.6 mmol) were suspended in dichloromethane and stirred at room temperature for 2 hours. The mixture was diluted with dichloromethane (500 mL) and washed with saturated NH4Cl (2×200 mL), saturated NaHCO3 (2×200 mL) and brine (200 mL). The organics were dried over MgSO4 and concentrated under reduced pressure to afford the crude product as yellow foam.
