Procedure

A solution of 6.6 g. of 4,4-dimethyl-3-oxo-5-phenylpentanal in 25 ml. of dry benzene was treated with 4.7 g. of thionyl chloride and refluxed for 21/2 hours. Solvent was evaporated and the residue was distilled under reduced pressure to afford 5.8 g. of the title product as a colorless oil, B.P. 86°-90°/0.1 mm. λmaxfilm 3.45, 5.92, 6.32, 6.70, 6.82, 9.30, 9.48, 10.65, 11.95, 12.50, 13.0, 13.54 and 14.23 μ.
