Ammonia → N-[(1S)-2-Amino-1-methyl-2-oxoethyl]-3-(4-{[4-[5-fluoro-2-(methloxy)phenyl]-2-hydroxy-4-methyl-2-(trifluoromethyl)pentyl]amino}-6-methyl-1H-indazol-1-yl)-N-methylbenzamide

Participants

Reaction Steps

N,N-Diisopropylethylamine (0.044 mL, 0.25 mmol) and HATU (20.1 mg, 0.053 mmol) were added to a solution of N-{[3-(4-{[4-[5-fluoro-2-(methyloxy)phenyl]-2-hydroxy-4-methyl-2-(trifluoromethyl)pentyl]amino}-6-methyl-1H-indazol-1-yl)phenyl]carbonyl}-N-methyl-L-alanine (32.4 mg, 0.05 mmol) in DMF (1 mL) and the solution stirred at room temperature under nitrogen for 10 min. Ammonia in dioxan (5M, 1.01 mL, 5.05 mmol) was added and the mixture stirred at room temperature overnight. The mixture was diluted with methanol and purified by mass directed autopreparation (System B) and product containing fractions were partitioned between dichloromethane and aqueous sodium bicarbonate. The organic phase was separated, combined with a second dichloromethane extract, washed twice with water, dried through a hydrophobic frit and evaporated to give the title compound (11 mg).
