PROCEDURE

实验过程

A mixture of dimethyl (m-phenylbenzyl)malonate (1.00 g) and lithium chloride (0.285 g) in water (0.12 ml) and dimethylsulphoxide (8.5 ml) was heated at 165° C. for 3 hours then allowed to cool, poured into water and extracted with ether. The extracts were washed with water, dried, concentrated, and chromatographed using 10% ether in petrol as eluant to give methyl 3-(m-phenylphenyl)propanoate (0.65 g, 81%) as a colourless oil which solidified on standing, melting point 29°-30° C.
