実験手順
1M Hydrochloric acid (5 mL) was added to a solution of 3-{[5-(azetidin-1-ylcarbonyl)pyrazin-2-yl]oxy}-5-[((1S)-2-{[(1,1-dimethylethyl)(dimethyl)silyl]oxy}-1-methylethyl)oxy]-N-(5-methylpyrazin-2-yl)benzamide (90 mg, 0.16 mmol) in methanol (5 mL) and the mixture stirred at RT for 1 hour. The methanol was removed in vacuo, the residue adjusted to pH6 and then extracted into ethyl acetate (3×50 mL). The combined organics were washed with brine (50 mL), dried (MgSO4), and reduced in vacuo to give a yellow oil which was chromatographed on silica, eluting with 0-5% methanol in ethyl acetate, to give the desired compound as a white foam (28 mg).
