Reaction Conditions

Reaction Steps

To a solution of ammonium acetate (1258 g) in methanol (8.54 () were added 2-(1-ethoxycarbonyl-1-methylethoxyimino)propanedinitrile (854 g) and 28% ammonia water (568 ml). After the mixture was stirred at 20° C. for 15 hours, methanol was evaporated under reduced pressure. The residue was dissolved in a mixture of water (8 l) and tetrahydrofuran (8 l). After the aqueous layer was saturated with sodium chloride, the organic layer was separated and dried over magnesium sulfate. Acetic acid (368 g) was added to the solution, then the mixture was evaporated under reduced pressure, and the residue was triturated with diisopropyl ether (8 l) to give 2-cyano-2-(1-ethoxycarbonyl-1-methylethoxyimino)acetamidine acetate (689.1 g).
