To a vigorously stirred solution of furfurylamine (2.78 g) in ethyl acetate (40 ml) was added sodium hydroxide (1.15 g) in water (45 ml), followed immediately by the addition of a solution of 3,5-dichlorobenzoyl chloride (6.0 g) in ethyl acetate (20 ml). Following the mild exothermic reaction the ethyl acetate layer was removed, dried (MgSO4), and evaporated. Crystallisation of the residue from cyclohexane gave the product (6.6 g) as colourless needles.
