A convergent synthetic plan was employed (Scheme 1). The benzothiazole fragment (A) was prepared via a Hantzsch condensation, while the pyrazolo[1,5‑a]pyridine fragment (B) was constructed through a cyclocondensation of 2‑aminopyrazine with an appropriate β‑ketoester. The two fragments were linked via a coupling step. Full experimental details are provided in the Supporting Information (SI). Purity > 98 % was confirmed by HPLC‑UV
