Versuchsvorschrift

A mixture of commercially available benzamide 35 and glyoxylic acid 41 was heated at reflux in acetone to give pure N-benzoyl-2-hydroxyglycine 65 as a colourless solid in quantitative yield (Scheme 4.12). The 1H n.m.r. spectrum supported formation of the α-hydroxyglycine derivative 65 with the appearance of a methine (H2) doublet and broad amide (NH) doublet at δ 5.60 and δ 9.26 respectively. Spectroscopic data were in agreement with those reported in the literature.209
