Procedure

Following the general procedure of Example 8, 196 mg (0.58 mmole) of 5,5-bis(4-fluorophenyl)-4-(1 H-tetrazol-1-yl)-2,4-pentadienal was condensed with two equivalents (1.2 mmoles) of the dianion of ethyl acetoacetate. The product thereby produced was purified by silica gel chromatography using ethyl acetate-hexanes as eluent to yield 173.8 mg (61.5%) of the title compound.
