Reaction Steps

A solution of 3-[6-(4-fluoro-phenyl)-pyrazolo[1,5-a]pyridin-3-yl]-phenylamine (Example 118, 50 mg, 0.16 mmol), Et3N (45 μL, 0.32 mmol) and ethyl isocyanate (26 μL, 0.32 mmol) in dry DME (2 ml) was stirred and heated at 60° C. under N2 for 24 hours [Further ethyl isocyanate (30 μL) was added after 7 hours]. The reaction mixture was evaporated and dried under vacuum to give the title compound (55 mg, solid). 1H NMR (400 MHz, DMSO-d6): 9.09 (1H, s), 8.53 (1H, s), 8.36 (1H, s), 8.02 (1H, d), 7.93-7.83 (3H, m), 7.72 (1H, dd), 7.38-7.29 (3H, m), 7.27-7.22 (2H, m), 6.15 (1H, t), 3.19-3.09 (2H, m), 1.08 (3H, t).
