In the title compound, CHO, the 2-meth-oxy-phenyl ring is tilted by 50.67 (3)° with respect to the naphthyl ring system. The central pyran ring has an envelope conformation with the C atom bearing the pendant ring system as the flap. The meth-oxy group attached to the benzene ring is slightly twisted [C-C-O-C = -15.2 (1)°] from the ring. In the crystal, weak C-HO inter-actions link the mol-ecules into (7) chains propagating along [101].

在标题化合物CHO中，2-甲氧基苯基环相对于萘环系统倾斜50.67 (3)°。中心吡喃环具有信封式构象，带有侧链环系统的C原子作为瓣片。连接到苯环上的甲氧基与环稍有扭曲[C-C-O-C = -15.2 (1)°]。在晶体中，弱的C-HO相互作用将分子连接成沿[101]方向延伸的(7)链。
