Procedure
Triethylamine (0.65 ml; 4.69 mmol; 1.49 eq.) is added to a suspension of (2′-amino-4′-methyl-4,5′-bi-1,3-thiazol-2-yl)acetonitrile (1 000 mg; 3.15 mmol; 1 eq.) and CDI (1 372.3 mg; 8.46 mmol; 2.68 eq.) in dry DCM (65 ml). DMF (4 ml) is added and the mixture is heated at 45° C. for one night. The reaction is cooled down to rt. The resulting precipitate is filtered and washed with Et2O, affording N-[2-(cyanomethyl)-4′-methyl-4,5′-bi-1,3-thiazol-2′-yl]-1H-imidazole-1-carboxamide, which is used in the next step without further purification (822.8 mg; 79%).
