3,4‐Dihydroquinazoline derivatives have been known to be the novel and potent T‐type calcium channel blockers. From a systematic variation of 3,4‐dihydroquinazoline derivative 5c (KYS05043), plausible SAR results were established. It was revealed that a 5‐(dimethylamino)pentylamino group at R1, a biphenyl group at R2, and a benzyl amido group at R3 in the 3,4‐dihydroquinazoline backbone are closely
