2-iodo-3-methylbutane

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

Procedure: 3-Naphthylcarbonyl-5,5-diphenylimidazolidine-2,4-dione (51 mg) was dissolved in DMF (0.4 mL), and sodium hydride (60%, in oil) (5 mg) was added. Then, methylisobutyl iodide (23 mg) was added, and the mixture was stirred at room temperature overnight. Ethyl acetate (9.5 mL) was added to the reaction solution, separated out white precipitates were filtered, and the filtrate was concentrated and purified by silica gel chromatography (hexane:ethyl acetate=2:1) to obtain 20 mg of white crystals. separated out white precipitates were filtered the filtrate was concentrated purified by silica gel chromatography (hexane:ethyl acetate=2:1)

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