Participants

Reaction Steps

By the procedure of Example 1(i), 1,3-dibromopropane was reacted with 1-methyl-2-thioxo-4,5-imidazolidinedione to yield 1-(3-bromopropyl)-3-methyl-2-thioxo-4,5-imidazolidinedione which, on reaction with thiourea by the procedure of Example 1(ii) gave S-[6-(1-(3-methyl-4,5-dioxo-2-thioxoimidazolidinyl))propyl]isothiourea hydrobromide. Hydrolysis of the latter compound by the procedure of Example 1(iii) and recrystallisation of the product from water gave the title compound, m.p. 141°-143°.
