実験手順

A cold solution of hydroxylamine.hydrochloride (15 g, 0.22 mol) in H2O (50 ml) was mixed with a cold solution of NaOH (20 g, 0.5 mol) in H2O (150 ml) and then 4-methoxy-3-methylbenzaldehyde (30 g, 0.2 mol) was added in a steady stream. After stirring at room temperature for 30 minutes, the solution was saturated with CO2. The separated solid was collected, washed with H2O, and dried to yield 30.9 g (94%) of 20; m.p. 70°-2° C.
