Versuchsvorschrift
4.5 parts of N,N-dimethyl-N'-(4-chloro-3-cyano-thien-2-yl)-formamidine in a mixture of 20 parts of formic acid and 20 parts of water are heated at the boil for 1 hour. After the mixture has cooled to room temperature, the product is filtered off under suction, washed with water and dried. 3 parts (77% of theory) of N-(4-chloro-3-cyanothien-2-yl)-formamide are obtained.
