Thionyl chloride (0.12 mol) in 60 mL of CH2Cl2 was added to a stirred solution of 2-phenylbutyric acid (16.4 g, 0.10 mol). A catalytic amount of DMF was added and the reaction was allowed to continue overnight at room temperature. The volatiles were removed under vacuum and the residual liquid was vacuum distilled to yield 12.4 g (68%) of 2-phenylbutyryl chloride. IR (neat) 1798 cm-1 (C=O).
