Versuchsvorschrift

To a solution of 3-(5-(2-chloropyrimidin-4-yl)-2-morpholinothiazol-4-yl)-2-fluoroaniline (3 g, 7.6 mmol) in DCM (50 mL) was added pyridine (10 mL). The mixture was cooled to 0° C. Furan-2-sulfonyl chloride (1.4 g, 8.4 mmol) in DCM (5 mL) was added dropwise to the mixture. The reaction was stirred at rt overnight. Then the reaction was washed with water (100 mL), and extracted with DCM (2×100 mL). The organic layer was washed with brine, dried over anhydrous Na2SO4, filtrated and concentrated under reduced pressure to give the crude product, which was purified by column chromatography on silica gel (petroleum ether:EtOAc 4:1) to afford the title compound of Step A (2.5 g, 63% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 8.07 (d, J=5.5 Hz, 1H), 7.59-7.66 (m, 1H), 7.42-7.75 (br, 1H), 7.13-7.20 (m, 2H), 7.02 (d, J=5.5 Hz, 1H), 6.93-6.98 (m, 1H), 6.37-6.42 (m, 2H), 3.50-3.57 (m, 4H), 3.72-3.78 (m, 4H). MS (ES+): 522 [M+H]+.
