Reaction Steps

In a 100 ml three necked flask is placed 10 g (0.055 mol) of N-methallyl-5,5-dimethylhydantoin in 100 ml DMF under nitrogen. The solution is cooled to 15° C. and 2.7 g of sodium hydride/mineral oil is added. The reaction is stirred for 2 hours at 15° C. and then warmed to 25°C. Methallyl chloride (5.1 g, 0.056 mol) is added dropwise over 10 minutes, keeping the temperature at 30° C. The reaction is stirred overnight, then poured into 200 ml water, extracted with 2 X 100 ml ether and dried over magnesium sulfate. After removing the ether in vacuo, the residue is distilled under vacuum (BP 100°-105°0 C. 0.3 mm Hg) to give 11.9 g N,N'-bismethallyl-5,5-dimethylhydantoin.
