Reaction Conditions:

with 1,3-dibromo-5,5-dimethylimidazolidine-2,4-dione at 70; for 40 h;

Steps:

3.2.1. General Procedure for the Esterification between Carboxylic Acids and Alcohols

General procedure: The mixture of carboxylic acid, alcohol, and 1,3-dibromo-5,5-dimethylhydantoin was stirredin a 25 mL reactor tube at 70 °C for 2-40 h. After reaction completion, the mixture was cooled toroom temperature and the alcohol was evaporated under reduced pressure. The isolation procedurewas as follows, except where noted dierently in the Supporting Information. The residue wasdissolved in 10 mL ethyl acetate and washed with a mixture of 1 mL saturated NaHCO3(aq), 1 mLsaturated Na2S2O3(aq), and 10 mL distilled water, and the water phase was extracted with ethyl acetate(2 10 mL). The organic layers were combined, dried over Na2SO4, and the solvent was evaporatedunder reduced pressure
