合成路线1
The reaction of N1-amidino-N3-phenylthiourea (I) with 3-(benzyloxy)phenacyl bromide (II) in ethanol/acetone gives the N1-amidino-S-[2-(3-benzyloxyphenyl)-2-oxoethyl]-N3-phenylisothiourea (III), which without isolation is cyclized to the target aminothiazole by means of TEA.

合成路线2
The reaction of aniline (I) with di(2-pyridyl)thione (DPT) gives the corresponding isothiocyanate (II), which is condensed with cyanamide (III) and 2-bromo-1-(3-benzyloxyphenyl)ethanone (IV) by means of NaOMe to yield the adduct (V). This compound, without isolation, cyclizes to the target thiazole.
