HCID 21317571Ethyl 5-carboxy-9-acetoxytetradecyloxyacetate

Procedure

This compound is prepared essentially by the method described in Example 1, Step D except that the di-tert.-butyl 2-(4-acetoxynonyl)-2-(6-ethoxycarbonylhexyl)-malonate of the example is replaced by di-tert.-butyl 2-(4-acetoxynonyl)-2-[4-(ethoxycarbonylmethoxy)-butyl]malonate. The title compound is purified by column chromatography on silica gel.
