Procedure

To a suspension of 2-(6-methylpyrazolo[5,1-b][1,3]thiazol-7-yl)-4-phenyl-1,3-thiazole-5-carboxamide (340 mg, 1.0 mmol) obtained above in DME (10 mL) was added 2,4-Bis(4-methoxyphenyl)-2,4-dithioxo-1,3,2,4-dithiadiphosphetane (485 mg, 1.2 mmol), and the mixture was stirred at 80° C. for 1 h. The reaction mixture was allowed to cool to rt, and then were added EtOAc (15 mL) and 1N hydrochloric acid (15 mL) and then the resulting suspension was filtered. The residue was washed with water (5 mL) and EtOAc (5 mL) to give the title compound (172 mg, 48%) as a yellow solid.
