Reaction Steps
Add dropwise trimethylacetyl chloride (3.3 mL, 27 mmol) to a mixture of 4-aminobenzonitrile (2.92 g, 24.7 mmol) and triethylamine (3.8 mL, 27 mmol) in anhydrous DCM (25 mL) at 0° C. Stir the mixture to room temperature overnight. Partition the reaction mixture between DCM (500 mL) and water (250 mL) and extract the aqueous phase with DCM (250 mL). Wash the combined organic extracts with water (3×250 mL), dry over Na2SO4, filter and concentrate in vacuo to obtain the desired intermediate (5 g, 100%). MS (ES+) m/z: 203.2 (M+H)+.
