Методика

The general procedure of Example 9 was repeated except that the ethyl 9,9-bis(4-fluorophenyl)-5-hydroxy-8-(5-phenyl-1H-tetrazol-1-yl)-3-oxo-6,8-nonadienoate utilized therein was replaced by 2.0 g of 9.9-bis(4-fluorophenyl)-5-hydroxy-8-(5-methyl-1H-tetrazol-1-yl)-3-oxo-6,8-nonadienoate and there was thereby produced 1.25 g (63%) of the title compound after purification by silica gel column chromatography with ethyl acetate in hexanes as eluent.
