Versuchsvorschrift

3-{[5-(Azetidin-1-ylcarbonyl)-3-chloropyridin-2-yl]oxy}-5-[((1S)-2-{[(1,1-dimethylethyl)(dimethyl)silyl]oxy}-1-methylethyl)oxy]-N-[1-(1-methylethyl)-1H-pyrazol-3-yl]benzamide (142 mg, 0.23 mmol) in methanol (2 mL) was stirred with 3.5M hydrochloric acid (0.2 mL, 0.68 mmol) for 1 hour. The solution was neutralised with saturated sodium bicarbonate solution and the organic solvent was removed under reduced pressure. The residue was extracted with ethyl acetate (3×10 mL), dried (MgSO4), filtered and the solvent removed under reduced pressure. The residue was purified by chromatography on silica, eluting with 75-100% ethyl acetate in hexane, to give the required product as a white foam (99 mg).
