Reaction Steps

In this operation a suspension of 1-formyl-2-(β-styrenesulfonyl)hydrazine (4.98 g, 22 mmol) in 6 N HCl (44 cc) was stirred for 4.5 hr at 50°-55° C. After cooling a small amount of insoluble material was removed by filtration. The filtrate was added all at once to a stirred solution of glyoxylic acid monohydrate (2.4 g, 26 mmol) in water (180 cc), and stirring was continued for 3 hr. The white crystalline solid which had precipitated was collected by filtration and air dried to give 3.0 g of the product compound, m.p. 141° (dec.).
