Abstract
2-Alkyl-4-amino-5-formylaminomethylpyrimidine is produced in a higher yield and using less process steps than the known methods by subjecting .beta.-aminopropionitrile to formylation in the presence of metal alcoholate, subjecting the resulting metal salt of .alpha.-formyl-.beta.-formylaminopropionitrile to alkylation or acylation, followed by allowing the thus produced .alpha.-alkoxy (or acyloxy)-methylene-.beta.-formylaminopropionitrile to react with an amidine.
