چکیده
In the mol-ecule of the title compound, C(22)H(22)ClN(3)O(2), the three fused rings of the benzofuro[3,2-d]pyrimidine system are almost coplanar. This ring system is oriented with respect to the substituted benzene ring at a dihedral angle of 79.05 (3)°. Intra-molecular C-H⋯N hydrogen bonding results in the formation of a six-membered ring. In the crystal structure, π-π stacking inter-actions involving the furan, pyrimidinone and benzene rings are present [centroid-to-centroid distances in the range 3.258 (1)-3.870 (1) Å].
