Reaction Steps
In a 250 mL round bottom flask a mixture of 3-cyano-4-fluorobenzoic acid (7.75 g, 0.047 mol) and thionyl chloride (28 mL, 0.38 mol, 8 eq) was heated to 80° C. for 1 h. The reaction mixture was concentrated in vacuo to give 8.6 g of 3-cyano-4-fluorobenzoyl chloride which can be used in the next step without further purification. 1H NMR (400 MHz, CDCl3): δ 8.49-8.43 (m, 1H), 8.42-8.36 (m, 1H), 7.44 (t, 1H).
