5-[(4-methylphenyl)methylidene]imidazolidine-2,4-dione

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 5-(p-Methylbenzylidene)-hydantoin was prepared in the same manner as in Example 4, except that 31.3 g (0.25 mol) of taurine and 60.0 g (0.50 mol) of p-tolualdehyde were used in lieu of glycine and p-hydroxybenzaldehyde, respectively. During the reaction, the pH of the reaction mixture was 9.8 to 9.6. During the reaction
