실험 절차
tert-butyl ({4-[2-(1-azetidin-3-yl-1H-pyrazol-5-yl)-4-chlorophenoxy]-3-cyanophenyl}sulfonyl)1,3-thiazol-4-ylcarbamate (Preparation 679, 200 mg, 0.326 mmol) was stirred in 4M hydrogen chloride solution in 1,4-dioxan (10 ml) at room temperature for 2 hours. The reaction mixture was concentrated in vacuo and the residue was partitioned between methyl-t-butyl ether (80 ml) and water (40 ml). The aqueous layer was neutralized to pH=7 by adding sodium hydrogen carbonate and was then concentrated in vacuo. The crude product was purified by column chromatography on silica gel using dichloromethane:methanol:0.880 aqueous ammonia, 90:10:1 to 70:30:3. This gave a buff powder (65 mg) which was triturated with methyl tert-butyl ether to give the title compound as a buff powder, 55 mg.
