Methyl iodide → Methyl Benzoate

Participants

Reaction Steps

Alternatively, treatment of isatoic acid XC with p-aminomethylbenzoic acid in water and triethylamine affords benzoic acid XCIII. Treatment of XCIII with sodium hydroxide, dioxane, methylchloroformate, and methanol affords an intermediate quinazolinedione carboxylic acid, the acid moiety of which is then converted to the anilinylamide moiety of XCIV using procedures analogous to those described for Scheme 16 above. Alternatively, the intermediate quanzolinedione carboxylic acid in DMF is treated with potassium carbonate and methyl iodide to produce an intermediate benzoic acid methyl ester, which is converted to an intermediate benzoic acid by treatment with sodium hydroxide, methanol, and water. The benzoic acid is then converted to the corresponding anilinylamide XCV using procedures analogous to those described for Scheme 16 above.
