実験手順

To a 25 ml round-bottomed flask was charged 3-[(1S)-2-tert-butoxy-1-methylethoxy]-N-(1-methyl-1H-pyrazol-3-yl)-5-[4-(methylsulfonyl)phenoxy]benzamide (498.4 μmol, 250.0 mg). This was dissolved in methanol (4 ml) and HCl (4 ml) was added to the flask in one portion. The reaction was heated to 50° C. for 1.5 hours. Solvent was removed in vacuo to yield a colourless solid that quickly changed to liquid form on standing. The liquid was dissolved in iPrOAc (10 ml) and water (10 ml). The aqueous layer was extracted with further iPrOAc (10 ml). The combined organic layer was dried with MgSO4 and the solvent was removed in vacuo to yield crude title product (142 mg; 63.95% yield) as a white foamy solid.
