Reaction Steps

Phenyl chloroformate (0.036 mL, 0.29 mmol) was added to a mixture of 5-[(2-fluorophenyl)amino]-N-(6-piperazin-1-ylpyridin-3-yl)-1,3,4-oxadiazole-2-carboxamide (Intermediate 41, 100 mg, 0.26 mmol) and triethylamine (0.07 mL, 0.52 mmol) in DMF (1.5 mL). The mixture was stirred for 2 h then directly purified by reverse phase HPLC eluting with a gradient of acetonitrile/water containing 0.2% TFA to give the title compound (40 mg, 31%) as a solid; 1H NMR δ 10.95 (1H, s), 10.73 (1H, s), 8.50 (1H, s), 8.05-7.95 (2H, m), 7.45-7.10 (8H, m), 6.90 (1H, d), 3.80-3.60 (8H, m); MS m/e MH+ 504.
