実験手順

Sodium cyanide (0.245 g, 5 mmol) was added to a mixture of 4-aminobenzoic acid (0.274 g, 2 mmol) and cyclobutanone (0.21 g, 3 mmol) in 90% acetic acid (4.5 ml). The reaction mixture was stirred at room temperature for 15 hours. The mixture was washed with aqueous HCl (pH 2) and extracted with ethyl acetate. The organic layer was dried over magnesium sulfate and concentrated to dryness under vacuum to yield 4-(1-cyanocyclobutylamino)benzoic acid (51a) (0.426 g, 1.97 mmol, 99%) as a white solid.
