(S)-2-{[5-(2,4-Difluorophenoxy)-1-isobutyl-1H-indazole-6-carbonyl]-amino}-4-[(2-methoxyethyl)-methylamino]-butyric acid methyl ester (0.023 g, 0.043 mmol) and NaBH4 (0.016 g, 0.43 mmol) were dissolved in THF/MeOH (7 mL, 5:2) and heated to 70° C. in a sealed vial for 5 hours. The mixture was cooled to room temperature, concentrated under reduced pressure and chromatographed eluting with TEA/ethyl acetate (1:4) to provide 0.007 g of the product as viscous oil (31% yield). MS (APCI+) m/z 505 (M+1) detected.
