Reaction Steps

A mixture of 4-fluoropiperidine×HCl (67 mg, 0.48 mmol), DIPEA (0.64 ml, 3.73 mmol), N-(4-fluoro-3-chloro-phenyl)-2-fluoro-4-methylamino-5-nitro-benzoic acid amide (150 mg, 0.44 mmol) and MeCN (5 mL) is stirred for 6 h at reflux. Then the mixture is concentrated, diluted with EtOAc, washed with water and concentrated.
