摘要：
Benzopyran derivatives are known to possess various biological activities. In the title compound, C20H15NO3, the benzopyran ring is essentially planar and the dihedral angle between the benzopyran and phenyl rings is 56.5 (1)degrees. In the crystal, the carbonyl and methoxy O atoms are involved in weak C-H . . .O-type intermolecular interactions.
