실험 절차

A solution of toluene-4-sulfonic acid 2-[1-benzyl-3-(naphthalene-1-sulfonyl)-1H-indazol-5-yloxy]-ethyl ester (0.444 g, 0.725 mmol) and isopropylamine (2.0 mL, 23 mmol) in THF (8 mL) was stirred at 70° C. in a sealed tube for 3 hours. More isopropylamine (2.0 mL, 23 mmol) was then added, and the reaction mixture was stirred at 80° C. in a sealed tube for 16.5 hours. After cooling somewhat, the reaction mixture was solvent evaporated and partitioned in ethyl acetate and aqueous sodium bicarbonate. The organic phase was then washed with water and brine. It was dried with anhydrous magnesium sulfate, filtered and concentrated. Drying at 80° C. in vacuo for 20 minutes gave {2-[1-benzyl-3-(naphthalene-1-sulfonyl)-1H-indazol-5-yloxy]-ethyl}-isopropyl-amine as a yellow semi-solid (0.290 g, 80.1% mmol). This was dissolved in chloroform, and ethereal hydrochloride was added. The mixture was concentrated and dried for 13 hours in vacuo at 81° C. The result was the hydrochloride as a buff foam (0.273 g); Mass Spectrum (+EI, [M+H]+) m/z 500.
