该中间体在本合成路线中的序号：(III)

Isocyanate (II) was prepared by treatment of 4-tert-butylbenzylamine (I) with phosgene in refluxing toluene. Subsequent coupling of isocyanate (II) with 4-(2-phthalimidoethoxy)-3-methoxybenzylamine (III) furnished urea (IV). The phthaloyl protecting group was then removed by hydrazinolysis. The resulting amine was finally converted to the corresponding hydrochloride salt.
