Versuchsvorschrift

N-(4-Methoxybenzyl)-5-(3-[(1S)-2-methoxy-1-methylethoxy]-5-{5-[(5S)-5-methyl-4,5-dihydro-1,3-oxazol-2-yl]-1H-pyrrol-2-yl}phenoxy)-N-methylpyridine-2-sulfonamide (292 mg, 0.47 mmol) synthesized in Example (121c) was dissolved in trifluoroacetic acid (2 mL), and stirring was carried out at 45° C. for 1 hour. The solvent was distilled off under reduced pressure, methylene chloride and triethylamine were added in small portions to the residue, and the solvent was distilled off again under reduced pressure. The resulting residue was purified using silica gel column chromatography (elution solvent: methanol/methylene chloride=0%-4%) to afford the desired compound (208 mg, yield 88%) as a white solid.
