Participants

Reaction Steps

Ethyl 6-(bromomethyl)-4-[4-cyano-2-(methylsulphonyl)phenyl]-2-oxo-1-[3-(trifluoromethyl)-phenyl]-1,2,3,4-tetrahydropyrimidine-5-carboxylate (150 mg, 0.256 mmol; Example 19A) was initially charged in dioxane (3.5 ml). Phenylhydrazine (83.0 mg, 0.767 mmol) was added dropwise to the reaction mixture, and the mixture was then stirred at boiling point for 3 h. The reaction mixture was then separated directly by preparative HPLC (Method 12). This gave 9 mg (6% of theory) of the target compound.
