2‑Aminobenzamide (1.0 eq) was condensed with 4‑fluorobenzoyl chloride (1.2 eq) in dry dichloromethane (DCM) in the presence of triethylamine (2 eq) at 0 °C → rt (4 h). Cyclization was achieved by heating the crude amide in polyphosphoric acid (PPA) at 120 °C for 2 h, affording the quinazolinone core (95 % yield). Once I have a better understanding of your
