Vinbarbital

An early application of this reaction to the preparation of barbiturates starts by the condensation of the ketone, I21, with ethyl cyanoacetate by Knoevenagel condensation. Alkylation of the product (122) with ethyl bromide by means of sodium ethoxide affords 123. Condensation of this intermediate with guanidine in the presence of sodium ethoxide gives the diimino analog of a barbiturate (124). Hydrolysis affords vinbarbital (111). > ... [Pg.271]
