Yield:3545-80-0 91.5%

Reaction Conditions:

with hydroxyamino hydrochloride in water monomer at 20; for 18 h;

Steps:

1.1 1) oxime acetic acid

106.5 g (0.72 mol) of a 50% aqueous solution of glyoxylic acid and50 g (0.72 mol) of hydroxylamine hydrochloride was stirred at room temperature for 18 h.The mixture was extracted with ether and the organic phase was dried over anhydrous sodium sulfate. Filtration, suspension steam concentration,The resulting crude product was recrystallized from ethyl acetate to give 59.6 g of colorless crystals S2 in 91.5% yield.
