Abstract: alpha -(o-Chlorophenyl)-aminomethylene- beta -formylaminopropionitrile, process for its preparation by reacting a metal salt of alpha -formyl- beta -formylaminopropionitrile with a salt of o-chloroaniline in an aqueous medium, and use of the product to prepare the compound of the formula by reaction with acetamidine. The pyrimidine thus obtained is an intermediate for the preparation of vitamin B1.
