In methanol; at 20 - 50℃; for 28h; | 2,6-Diamino-3-(2,2-difluorobenzodioxol-4-yl)pyrazine [C E N -89]; Step i; 2-[Cyano-(2,2-difluorobenzodioxol-4-yl)methyl]amino}acetamidine hydrobromide; Aminoacetamidine dihydrobromide (1.14 g, 4.9 mmol) was added in portions to a solution of 4-formyl-2,2-difluorobenzodioxole (1.0 g, 5.4 mmol) in methanol (25 ml). Potassium cyanide (0.32 g, 4.9 mmol) was then added in a single portion and the mixture was stirred at room temperature for 4h and then at 50 0C for 24 h. The mixture was cooled and the solvent removed in vacuo. The residue was slurried in ethyl acetate (25 ml) and water (14 ml) and the tan solid removed by filtration and dried. Yield 0.40 g |
