A mixture of commercially available acetamide 34 and glyoxylic acid 41 was heated at reflux in acetone to give pure N-acetyl-2-hydroxyglycine 42 as a viscous yellow oil in quantitative yield. The 1H n.m.r. spectrum supported formation of the α-hydroxyglycine derivative 42 with the appearance of a methine (H2) doublet and broad amide (NH) doublet at δ 5.39 and δ 8.65 respectively. Spectroscopic data were in agreement with those reported in the literature.195
