実験手順

To a solution of 3-fluoroaniline (10 g, 90.00 mmol) in acetone (40 ml) was added pyridine (18 g, 227.56 mmol) and 3-chloropropanoyl chloride (13.73 g, 108.14 mmol) and the reaction was stirred for 3 h at 55° C. The resulting solution was extracted with ethyl acetate (3×50 ml) and the organic layers were combined, dried over anhydrous magnesium sulfate, and concentrated in vacuo to afford 3-chloro-N-(3-fluorophenyl)propanamide as a yellow solid (13.21 g, 73%).
