Practical routes toward the synthesis of 2-halo- and 2-alkylamino-4-pyridinecarboxaldehydes
We recently required an efficient synthesis of 2-halo- and 2-alkylamino-4-pyridinecarboxaldehydes. Several routes to these compounds were investigated resulting in efficient and practical procedures from readily available and inexpensive starting materials.
