実験手順

To a solution of 2-amino-6-(methylamino)benzonitrile (example 156b) (0.14 g, 0.97 mmol) in 1,4-dioxane (3 mL) was added benzoyl isocyanate (0.17 g, 1.17 mmol). The reaction mixture was stirred at room temperature under nitrogen overnight. The obtained precipitate was filtered and dried under vacuum to give N-(2-cyano-3-(methylamino)phenylcarbamoyl)benzamide (57 mg, 20%). 1H NMR (400 MHz, DMSO-d6) δ 2.75 (d, J=4.4 Hz, 3H), 6.26 (d, J=4.8 Hz, NH), 6.43 (d, J=9.6 Hz, 1H), 7.40-7.43 (m, 2H), 7.51-7.55 (m, 2H), 7.63-7.65 (m, 1H), 8.01 (d, J=8.4 Hz, 2H), 11.23 (s, NH), 11.30 (s, NH). MS 295 (MH+).
