In a flask, under a nitrogen blanket, were placed 7.43 g (0.29 mole) of the product of Example 2 and 50 ml methylene chloride. Then, 3.07 g (0.031 mole) of 2,2,2-trifluoroethanol was added in a way so as to maintain the temperature at about 40° C. After the addition was complete, the flask was placed in an oil bath at 60° C. and most of the methylene chloride was evaporated. The product was allowed to stand at the same temperature for one hour and the remainder of the solvent stripped off under vacuum. There was obtained 9.09 g (95% of theoretical yield) of a white crystalline solid. Analysis for aluminum showed 8.36% Al. The theoretical value was 8.33%.
