Reaction Steps

To a solution of 5-(2,4-difluorophenoxy)-1-isobutyl-1H-indazole-6-carboxylic acid 2,5-dioxopyrrolidin-1-yl ester (32.0 g, 72.2 mmol) and 2-amino-4-dimethylaminobutyric acid methyl ester dihydrochloride (19.35 g, 83.0 mmol) in dichloromethane was added triethylamine (35 mL, 253 mmol) and the mixture stirred at room temperature for 4 hours. The reaction mixture was concentrated under reduced pressure and diluted with dichloromethane (400 mL). The solution was 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.
