Reaction Steps

A mixture of methyl phenylglyoxylate (25.5 g), hydroxylamine hydrochloride (11.3 g), triethylamine (22.8 ml) and methanol (300 ml) was stirred for 17 hours at 60° C. The reaction mixture was concentrated, and the residue was diluted with water and extracted with ethyl acetate. The ethyl acetate layer was washed with water, (MgSO4), and then concentrated. The residual crystals were recrystallized from ethyl acetatehexane to obtain methyl E-2-hydroxyimino-2-phenylacetate (3.58 g, yield 13%) as colorless crystals. m.p. 151-153° C.
