実験手順
Trifluoroacetic acid (1 mL) was added to a solution of 1,1-dimethylethyl 3-{[(3-[(1,1-dioxido-3,4-dihydro-2H-5,1,2-benzoxathiazepin-7-yl)oxy]-5-{[(1S)-1-methyl-2-(methyloxy)ethyl]oxy}phenyl)carbonyl]amino}-1H-pyrazole-1-carboxylate (47 mg, 0.08 mmol) in DCM (8 mL) and stirred at RT for 2 hours. The solvent was removed in vacuo, DCM (20 mL) added and the mixture washed with water (20 mL), a saturated solution of sodium bicarbonate (20 mL), brine (20 mL), dried (MgSO4), filtered and reduced in vacuo to give the desired compound as a white foam (39 mg).
