Crystal structure of ethyl 3-(4-chloro­phen­yl)-5-[(E)-2-(di­methyl­amino)­ethen­yl]-1,2-oxazole-4-carboxyl­ate

In the title compound, C(16)H(17)ClN(2)O(3), two mol­ecules, A and B, with different conformations, comprise the asymmetric unit. In mol­ecule A, the C=O group of the ester points away from the benzene ring [C—C—C=O = −170.8 (3)°], whereas in mol­ecule B, it points back towards the benzene ring [C—C—C=O = 17.9 (4)°]. The dihedral angles betweeen the oxazole and benzene rings also differ somewhat [46.26 (13) for mol­ecule A and 41.59 (13) for mol­ecule B]. Each mol­ecule features an intra­molecular C—H⋯O inter­action, which closes an S(6) ring. In the crystal, the B mol­ecules are linked into [001] C(12) chains by weak C—H⋯Cl inter­actions.
