실험 절차

1-chloro-N-(thiazol-2-yl)isoquinoline-6-sulfonamide (0.200 g, 0.614 mmol) and potassium carbonate (0.424 g, 3.07 mmol) were dissolved in DMF (4.09 ml). Morpholine (0.535 ml, 6.14 mmol) was added and the reaction was stirred overnight at 110° C. The reaction was diluted with water and extracted twice with ethyl acetate. The aqueous layer was acidified to a pH of about 1 with concentrated HCl solution and extracted twice with ethyl acetate. The aqueous layer was passed through an SCX ion exchange column (pre-wetted with methanol) (Biotage AB, Uppsala, SE), then the column was washed several times with methanol. The product was liberated with ammonia solution in methanol. The process was repeated with the aqueous filtrate and a new SCX column. The product-containing filtrates were combined and concentrated to afford crude product as an orange solid. The material was purified by silica gel chromatography (40 g column, gradient elution 0-10% MeOH:DCM) to afford 1-morpholino-N-(thiazol-2-yl)isoquinoline-6-sulfonamide as a light yellow solid. 1H NMR (400 MHz, DMSO-d6) δ=12.86 (br. s., 1H), 8.38 (d, J=1.9 Hz, 1H), 8.28-8.19 (m, 2H), 7.86 (dd, J=1.9, 8.9 Hz, 1H), 7.62 (d, J=5.5 Hz, 1H), 7.28 (d, J=4.6 Hz, 1H), 6.87 (d, J=4.6 Hz, 1H), 3.88-3.80 (m, 4H), 3.35-3.26 (m, 4H). m/z (ESI) 377.2 (M+H)+.
