合成路线1
2-(2-Thienyl)ethylamine (I) was protected as the N-Boc derivative (II) with Boc2O in CHCl3. Regioselective halogenation of the thiophene ring of (II) with concomitant Boc group cleavage by means of bromine in cold HOAc yielded the 5-bromothiophene (III). The thioimidazolide (VI) was prepared by reaction of 2-amino-5-chloropyridine (IV) with thiocarbonyl diimidazole (V). Finally, condensation of (VI) with amine (III) in hot DMF furnished the target thiourea.
