Versuchsvorschrift
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°. Hydrolysis of the latter compound and working up of the product by the general procedure of Example 1(iii) and conversion to the sulphate with ion-exchange resin (Amberlite IRA 400, sulphate form) gave the title product as a hygroscopic amorphous solid, m.p. 63°-65°.
