Reaction Steps

Treat a solution of 2-isobutylamino-3-nitro-6-[3-(4-fluorophenyl)pyrazol-4-yl]pyridine (1.25 g, 3.52 mmol) in dry DMF (15 mL) with 95% NaH (0.36 g, 14.3 mmol) at 0° C. for 15 min. Add morpholinoethylchloride hydrochloride (0.983 g, 5.28 mmol) and slowly warm to RT. Add additional NaH (0.36 g, 14.3 mmol), after 1 h and stir the reaction mixture for 24 h. Quench with MeOH (1 mL) and dilute with water (30 mL). Extract with EtOAc (100 mL), dry with MgSO4, and concentrate. Purify the residue (silica gel chromatography, eluting with hexanes:EtOAc 1:2) to give the title compound (1.35 g, 81%).
