실험 절차

A solution of ethyl 4-(3-((1S)-2-{[tert-butyl(dimethyl)silyl]oxy}-1-methylethoxy)-5-{[(1-methyl-1H-pyrazol-3-yl)amino]carbonyl}phenoxy)benzoate (3.78 g, 6.84 mmol) in THF (100 mL) was added to a solution of lithium hydroxide monohydrate (1.44 g, 33 mmol) in water (50 mL). The mixture was stirred at ambient temperature for 72 hours. 1M Hydrochloric acid was added until pH=2 and the mixture stirred for a further 1 hour. The THF was removed in vacuo and the solid precipitate filtered off, washed with water and dried in vacuo to give the desired compound (3.06 g).
