Trialkylamine salts of 3-chloro-1,1-dicyano-2-hydroxy-1-propene, where the trialkylamine has from 10 to 24 carbon atoms, a process for their preparation from malononitrile, chloroacetyl chloride, and a trialkylamine, and a process for the preparation of 2-amino-4-chloro-3-cyano-5-formylthiophene in which a trialkylamine salt of 3-chloro-1,1-dicyano-2-hydroxy-1-propene is cyclized with hydrogen sulfide or another sulfide and treated with a mixture of N,N-dimethylformamide and phosphoryl chloride, and the product is hydrolyzed by acid without being isolated previously.
