The title N-benzylphthalimide derivative, C16H13NO3, consists of two planar moieties, viz. the phthalimide system (r.m.s. deviation = 0.007 Å) and the phenyl ring, which make a dihedral angle of 84.7 (6)°. The methoxy group is almost coplanar with the phathalimide ring, as shown by the C—C—O—C torsion angle of −171.5 (2)°. In the crystal, the molecules are self-assembled via non-classical C—HO hydrogen bonds, forming a tape motif along [110].

In the title compound, C21H24N2O2Si, a new pyridazin-3(2H)-one derivative, the carbonyl group of the heterocyclic ring and the O atom of the silyl ether are located on the same side of the pyridazinone ring and the C—C—O—Si torsion angle is −140.69 (17)°. In the crystal, molecules are linked by pairs of strong N—HO hydrogen bonds into centrosymmetric dimers with graph-set notation R22(8). Weak C—Hπ interactions are also observed.
