5,5-Diphenyl-3-hydroxymethyl-2,4-imidazolidinedione (2 g, 0.0071 mol) was dissolved in 2-bromopropionyl chloride (8.5 g, 5 mL, 0.05 mol) by heating for 30 minutes on a 100°-110° C. oil bath. The reaction mixture was cooled, 20 mL of ethyl ether were added, and the resultant solution was extracted with aqueous potassium carbonate, dried and then crystallized. The product was obtained as a solid white substance (1 g, 34%), m.p. 112°-115° C. Anal. calc. for C19H17N2O4Br: C, 54.69; H, 4.11; N, 6.72; Br, 19.15. Found: C, 54.77; H, 4.15; N, 6.69; Br, 19.25. The product had the formula: ##STR77##
