実験手順

To a solution of 3.54 g (0.0510 mol) of hydroxylamine hydrochloride in a mixture of 10.2 mL (0.0510 mol) of 5 N NaOH, dioxane (50 mL), and 70% aq. acetic acid (100 mL), is added 6.79 g (0.0424) of N-[(dimethylamino)methylene]-4-methylbenzamide (prepared as described in J. Chem. Soc. Perkin. Trans. 1 1989, 589). The mixture is stirred at 90° C. for 1.5 h and the product is isolated from the cooled reaction mixture. MS 161 (M+H)+.
