Reaction Steps

5-(2-Phenylethyl)-2-thiouracil (1.8 g) was converted into 5-phenylethyl-2-methylthio-4-pyrimidone (m.p. 160°-161° ex ethanol) by the method described in Example 1(i). Reaction of this pyrimidone (1.55g) with 2-(5-methyl-4-imidazolylmethylthio)-ethylamine (1.1 g) by the method described in Example 1(ii) gave an oil which was dissolved in 2N hydrochloric acid, the solution evaporated to dryness and the residue recrystallised from methanol to give 2-[2-(5-methyl-4-imidazolylmethylthio)-ethylamino]-5-(2-phenylethyl)-4-pyrimidone dihydrochloride, m.p. 214°-218°.
