Participants

Reaction Steps

1.28 g (4.71 mmol) of 2-(4-chlorobenzoyl)-N-(2-methoxyethyl)-hydrazinecarboxamide from Example 13A are heated under reflux overnight in 10 ml 3 N aqueous sodium hydroxide. After cooling, it is acidified to about pH 2.5 with 1 N hydrochloric acid with ice-cooling and the resulting precipitate filtered off and dried in vacuo. 1.09 g (92% of theory) of the target compound, which is reacted without further purification, are thus obtained.
