Following a procedure analogous to the procedure described in Intermediate 13 using 2-propen-1-yl {3-[5-(2-chloro-4-pyrimidinyl)-2-(1,1-dimethylethyl)-1,3-thiazol-4-yl]-2,4-difluorophenyl}carbamate (2.962 g, 6.37 mmol) (from composite batches prepared as described above) the title compound of Step B was obtained (1.96 g, 81% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 8.67 (d, J=5.3 Hz, 1H), 7.09 (d, J=5.3 Hz, 1H), 6.88-7.02 (m, 2H), 5.23 (s, 2H), 1.45 (s, 9H); MS (ESI): 380 [M+H]+.
