white fine crystalline powder

2''-Fluoroacetanilide

Step 1: Synthesis of N-(2-fluorophenyl)acetamide To a solution of 2-fluoroaniline (5.0 g, 45.05 mmol) in dichloromethane (DCM, 225 mL) was sequentially added acetic anhydride (4.09 mL, 45.05 mmol) and triethylamine (7.55 mL, 54.05 mmol). The reaction mixture was stirred at room temperature for 6 hours. After completion of the reaction, the mixture was concentrated, diluted with ethyl acetate and washed with 1N hydrochloric acid (2 x 50 mL). The organic phase was dried with anhydrous sodium sulfate (Na2SO4) and concentrated to give N-(2-fluorophenyl)acetamide (6.20 g, 90% yield) as a white solid.LCMS analysis showed the molecular ion peak of the target product to be 153.99 (M + H)+.
