実験手順

To a solution of 2-propen-1-yl {3-[(2-chloro-4-pyrimidinyl)acetyl]-2-fluorophenyl}carbamate (20 g, 57 mmol) (Intermediate 20) in DMA (300 mL), NBS (10.2 g, 57 mmol) was added. The reaction mixture was stirred at rt for 1 h. Then morpholine-4-carbothioamide (9.2 g, 63 mmol) was added at 0° C. The mixture was stirred at rt for 2 h. The mixture was poured into water and extracted with EtOAc (1 L×3). The combined organic layers were washed with water and brine successively, dried over Na2SO4, filtered and concentrated under reduced pressure to give the crude product, which was purified by column chromatography on silica gel (DCM:petroleum ether 2:1) to afford the title compound (20 g, 83.5% yield). 1H NMR (400 MHz, CDCl3) δ ppm 8.20-8.27 (m, 1H), 8.19 (d, J=5.5 Hz, 1H), 7.20-7.26 (m, 1H), 7.08-7.12 (m, 1H), 6.92-6.98 (br, 1H), 6.62 (d, J=5.5 Hz, 1H), 5.90-6.03 (m, 1H), 5.25-5.41 (m, 2H), 5.65-5.70 (m, 2H), 3.57-3.63 (m, 4H), 3.77-3.86 (m, 4H). m/z (ES+): 476 [M+H]+
