실험 절차

2-[1-(tert-Butoxycarbonylamino-methyl)-6,7-dimethoxy-isoquinolin-4-ylamino]-thiazole-4-carboxylic acid ethyl ester (40 mg, 0.0818 mmol) in CH2Cl2 (1.0 mL) was treated with a 4.0 M HCl solution in dioxane (0.21 mL) at room temperature. After the reaction mixture was stirred at room temperature for 15 h, the suspension was filtered. The yellow solid was dried in vacuo to give 2-(1-aminomethyl-6,7-dimethoxy-isoquinolin-4-ylamino)thiazole-4-carboxylic acid ethyl ester hydrochloride salt (32.3 mg; 93%). 1H-NMR (D2O): δ, 8.81 (s, 1H), 7.46 (s, 1H), 7.18 (s, 1H), 7.13 (s, 1H), 4.63 (s, 2H), 4.14 (q, 2H, J=7.1 Hz), 3.86 (s, 3H), 3.83 (s, 3H), 1.20 (t, 3H, J=7.3 Hz); MS: calculated for C18H21N4O4S (M−Cl) 389.0; found: 389.0.
