Procedure

A flask was charged with 4-methyl-2-propyl-1H-imidazole from example 1.6 (140 mg, 1.13 mmol), Cs2CO3 (1.10 g, 3.39 mmol) and copper (I) iodide (108 mg, 0.56 mmol). A solution of (1R,2R)-N1,N2-dimethylcyclohexane-1,2-diamine (80 mg, 0.56 mmol,) and N-(4-bromothiazol-5-yl)acetamide from example 1.5 (250 mg, 1.13 mmol) in DMF (30 mL) was added under N2. The mixture was heated at 90° C. for overnight. It was concentrated and directly used for the next step without further purification.
