Reaction Steps

Dissolved 2-fluoroaniline (2.0 mL, 20.8 mmol, 1.05 eq) in 40 mL of anhydrous ether. Added Magnesium Sulfate (7146 mg, 59.3 mmol, 4 eq), 7 g of powdered mol sieves, and benzaldehyde (2.0 mL, 19.8 mmol). To this mixture was added pTsOH (18.8 mg, 98.9 μmol, 0.005 eq) and heated to reflux overnight. The reaction was cooled, filtered and concentrated to yield (E)-N-benzylidene-2-fluorobenzenamine. 1H NMR (400 MHz, CDCl3) δ ppm 8.55 (s, 1H), 7.95 (m, 2H), 7.52 (m, 5H), 7.18 (m, 4H).
