Procedure

By the procedure of Example 1(i), 1,4-dibromobutane is reacted with 1-methyl-2-thioxo-4,5-imidazolidinedione to yield 1-(4-bromobutyl)-3-methyl-2-thioxo-4,5-imidazolidinedione which, on reaction with thiourea by the procedure of Example 1(ii) gives S-[4-(1-(3-methyl-4,5-dioxo-2-thioxoimidazolidinyl))butyl]isothiourea hydrobromide, m.p. 113°-114°.
