In a flask were placed 10.27 g (55.75 mmoles) of the product of Example 1, under a nitrogen blanket. Then, 5.71 g (0.058 mole) of 2,2,2-trifluoroethanol was added dropwise. When the reaction mixture temperature reached 50° C., the flask was immersed in a chilled oil bath (0° C.) and the addition of fluoroalkanol was continued at a rate sufficient to maintain the temperature at 50°-55° C. After addition was completed, the reaction mixture was stirred for one hour at 55° C. The product was a viscous, colorless liquid. Analysis for aluminum showed 10.43% Al, which correlated well with the theoretical value of 10.58%.
