Participants

Reaction Steps

A mixture of 5-cyclopropylmethyl-2-pyrrolylglyoxylic acid ethyl ester (6.63 g.) and sodium hydroxide (1.32 g.) was heated in water (40 ml.) as described in Example 20. The resulting solution was cooled to 5° and the solid was filtered off and crystallized from acetone to give 5-cyclopropylmethyl-2-pyrrolylglyoxylic acid sodium salt hydrate (3.3 g.), M.P. 228°-232°. Found: C, 51.50; H, 5.19; N, 5.91. C10H10NO3Na. H2O requires: C, 51.50; H, 5.19; N, 6.01%.
