In the title compound, C 14 H 13 ClN 2 O, the fused hydro­pyrimidine ring adopts an envelope conformation with one of the methyl­ene C atoms at the flap. The three-membered ring is approximately perpendicular to the attached isoquinoline ring system, with a dihedral angle of 89.44 (11)°. In the crystal, mol­ecules are linked by a weak C—H⋯π inter­action, forming a helical chain along the  c  axis.
