Reaction Steps

To a solution of 2-nitro-4-(trifluoromethyl)benzenamine (3.00 g, 14.9 mmol, 1.0 equiv) in CH2Cl2 (90 mL) at 25° C., was added 3-chloro-2,2-dimethylpropanoyl chloride (3.9 mL, 29.8 mmol, 2.0 equiv) followed by triethylamine (4.2 mL, 29.8 mmol, 2.0 equiv). The solution was heated to 40° C. After 48 h, the solution was washed with water (50 mL), and brine (50 mL). After concentration in vacuo, the residue was purified by silica gel chromatography (1:10 hexanes:EtOAc to 1:5 hexanes:EtOAc) to afford 3-chloro-2,2-dimethyl-N-(2-nitro-4-(trifluoromethyl)phenyl)propanamide. MS-No (MH+) observed.
