Reaction Steps

Piperonal(15.0 g, 0.10 mol) was dissolved in methanol(150 ml), and hydroxylamine hydrochloride(10.5 g, 0.15 mol) and water(15 ml) were added thereto. The mixture was stirred for 1 hour at room temperature, then excess water was added, and the resulting mixture was stirred for further 1 hour. The white solid thus obtained was washed with water under reduced pressure, filtered, and dried to give (hydroxyimino)-(benzo[3,4-d]1,3-dioxolan-5-yl)methane(15.7 g, Yield 95%).
