실험 절차

Suspend {2-[7-(3-difluoromethylpheny)-isoquinoline-5-sulfonylamino]-ethyl}-carbamic acid tert-butyl ester in ethyl acetate (11 mL), and add an excess of 4 M HCl in 1,4-dioxane. Stir overnight, filter the precipitate, wash with dichloromethane, and dry under vacuum to give the desired compound as a white solid (0.092 g, 95% yield): 1H NMR (CD3OD): δ9.92 (s, 1H), 9.10 (d, J=7.0 Hz, 1H), 9.04 (m, 2H), 8.80 (d, J=7.0 Hz, 1H), 8.09 (m, 2H), 7.74 (m, 2H), 6.94 (t, J=52.1 Hz, 1H), 3.25 (m, 2H), 3.15 (m, 2H). Load the product onto ion exchange resin and elute with 1N NH3 in methanol and concentrate to dryness to give the free base. (Used in example 97).
