Experimental Crystal data

R factor = 0.038; wR factor = 0.094; data-to-parameter ratio = 18.5. In the title compound, C18H17FO2S, the dihedral angle between the plane of the benzofuran ring system (r.m.s. deviation = 0.013 Å) and that of the 4-fluorophenyl ring is 74.30 (5). In the crystal, weak C—H O and C—H F hydrogen bonds link the molecules into columns extending in direction [100]. Related literature For the crystal structures of related compounds, see: Choi et al
