4-Amino-2-chloro-6,7-dimethoxyquinazoline is a crucial intermediate in the synthesis of certain "zosin" drugs, specifically those used to treat hypertension and benign prostatic hyperplasia (BPH). These drugs, which include prazosin, terazosin, doxazosin, and alfuzosin, are alpha-1 adrenergic receptor antagonists. The quinazoline moiety in these drugs is derived from this intermediate.
