HCID 579898131,1-Dimethylethyl 4-[5-(2-chloro-4-pyrimidinyl)-4-(3-{[(2,6-difluorophenyl)sulfonyl]amino}-2-fluorophenyl)-1,3-thiazol-2-yl]-1-piperazinecarboxylateYield 38%

Procedure

Following a procedure analogous to Intermediate 6 using N-{3-[(2-chloro-4-pyrimidinyl)acetyl]-2-fluorophenyl}-2,6-difluorobenzenesulfonamide (2.00 g, 4.53 mmol), NBS (0.85 g, 4.75 mmol) and 1,1-dimethylethyl 4-(aminocarbonothioyl)-1-piperazinecarboxylate (2.22 g, 9.05 mmol) the title compound of Step A was obtained (1.16 g, 38% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 10.93 (s, 1H), 8.30 (d, J=5.49 Hz, 1H), 7.62-7.76 (m, 1H), 7.46 (td, J=7.46, 1.28 Hz, 1H), 7.38 (t, J=6.09 Hz, 1H), 7.32 (t, J=7.78 Hz, 1H), 7.25 (t, J=9.11 Hz, 2H), 6.46 (d, J=5.40 Hz, 1H), 3.56 (br. s., 4H), 3.47 (br. s., 4H), 1.42 (s, 9H). m/z (ES+): 668 [M+H]+.
