Participants

Reaction Steps

A solution of (3-methyl-1,2-oxazol-4-yl)(2-thienyl)methanone (6.00 g, 31.0 mmol) and hydroxylamine hydrochloride (5.40 g, 77.6 mmol) in pyridine (80 mL) was stirred 5 h at 50° C. then overnight at room temperature. After removal of the solvent in vacuo, addition of water (50 mL) and extraction with ethyl acetate (3×40 mL), the combined organic layers were dried over MgSO4 and concentrated in vacuo. The residue was purified on silica gel to afford N-hydroxy-1-(3-methyl-1,2-oxazol-4-yl)-1-(2-thienyl)methanimine [6.45 g, yield 99%; HPLC/MS: m/z=219 (M+H); log P(HCOOH)=1.75].
