Versuchsvorschrift
240 mg (0.970 mmol) of methyl 4-(aminothioxomethyl)-5-methylthiothiophene-2-carboxylate (Maybridge Chemical Co. LTD., Cornwall, U.K.) was reacted with 2-bromo-1-(4-chloro(3-pyridyl))ethan-1-one (1.06 mmol; 250 mg) in a manner similar to Example 22, step (a) to afford 286 mg (77% yield) of methyl 4-[4-(4-chloro(3-pyridyl))(1,3-thiazol-2-yl)]-5-methylthiothiophene-2-carboxylate.
