PROCEDURE

实验过程

97 g (0.2 mole) of 1,3-bis-(4-benzoyl-3-hydroxyphenoxy)-2-propanol were esterified analogously to Example 1 with 103 g (1.2 moles) of crotonic acid. After crystallization from an acetone/ethanol mixture (ratio by volume 1:2), 83 g (75 percent of theory) of 1,3-bis-(4-benzoyl-3-hydroxyphenoxy)-prop-2-yl crotonate were obtained in the form of fine white crystals having a melting point of 99° to 103° C. and a purity of 99 percent (HPLC). The structure of the compound obtained was confirmed by UV, IR and NMR spectra.
