Practical routes toward the synthesis of 2-halo- and 2-alkylamino-4-pyridinecarboxaldehydes
摘要:
We recently required an efficient synthesis of 2-halo- and2-alkylamino-4-pyridinecarboxaldehydes. Several routes to these compounds were investigated resulting in efficient and practical procedures from readily available and inexpensive starting materials. (C) 2001 Elsevier Science Ltd.

The present invention prepares imidazoles by the selective closure of a keto-amide to form the imidazolyl ring. In particular, the present invention selectively closes a keto-amide substituted with three rings to form a tri-substituted imidazole.
