Procedure
The subject compound is prepared using the general method of Example 1 except that 4.58 g (20 mmol) of glyoxylic acid p-acetamidobenzenesulfonylhydrazide was reacted with 2.4 g (26 mmol) of glyoxylic acid monohydrate in the presence of 1/2 cc conc. HCl and 200 cc acetonitrile. The desired product was obtained in a yield of 5.4 g, m.p. 136° (dec.).
