A mixture of N-(2,4-dibromothiazol-5-yl)acetamide from example 1.4 (0.35 g, 1.17 mmol), diethylamine (0.085 g, 1.17 mmol) and Raney Ni (0.14 g, 2.33 mmol) in ethanol (50 mL) was stirred at room temperature for 12 h in a 100 mL round-bottomed flask to give a black solution. The reaction mixture was filtered and concentrated to give the title compound (0.20 g, 0.91 mmol, 78%) as a yellow solid which was directly used for the next step without purification.
