Versuchsvorschrift

5-(2,4-Difluorophenoxy)-1-isobutyl-1H-indazole-6-carboxylic acid (17d; prepared according to Example 110) (0.022 g, 0.064 mmol) was stirred with HOBt (0.011 g, 0.070 mmol) and EDCI (0.014 g, 0.070 mmol) in dichloroethane (1 mL) for 10 minutes at room temperature. To this mixture was then added a suspension of (S)-methyl 4-((4-methoxybenzyl)(isopropyl)amino)-2-(tert-butoxycarbonyl)butanoate hydrochloride (0.025 g, 0.067 mmol) and triethylamine (0.054 mL, 0.384 mmol) in dichloromethane (2 mL). The mixture was stirred at room temperature for 16 hours. The solution was filtered through Celite and concentrated under reduced pressure. The crude oil was chromatographed eluting with 2% MeOH in dichloromethane with 1% triethylamine to provide 0.035 g of viscous pale yellow oil (89% yield).
