The title compound, C 12 H 12 N 2 O 2 , crystallizes in the triclinic space group P1 with two crystallographically independent molecules in the asymmetric unit. These two molecules differ slightly in the relative orientation of the phenyl and oxazoline rings. The molecular packing in the crystal is

In the title compound, C 11 H 9 N 3 O, the three cyano groups, the C atom of one of the three methyl groups and the dihydrofuran ring atoms lie on a crystallographic mirror plane. A weak C-HÁ Á ÁN interaction results in one-dimensional chains.
