Procedure

A solution of 155 g (0.75 mol) of 2-(3-chloropropyl)benzyl chloride 2 [Page, et al., J. Amer. Chem. Soc. 75:2053 (1953)], 91 g (0.81 mol) of 1,3-cyclohexanedione I [Aldrich Chem. Co. 10,160-5; Beilstein 7, 554], and 47 g of 85% KOH in 400 ml of methanol was refluxed 16 hours. After concentrating, the residue was partitioned between benzene and dilute aqueous NaOH solution. Acidification of the aqueous phase gave a solid that was recyrstallized from ethyl acetate to give 34 g of the dione 3, mp 143°-145° C.
