Procedure

1.75 g of lithium aluminum hydride are added in fractions under a stream of nitrogen to a solution of 4.4 g of the compound from Example 4 in 150 ml of tetrahydrofuran. After stirring for 1 hour, the mixture is hydrolyzed with 1.75 ml of water, 3.5 ml of a 10% (wt/wt) sodium hydroxide solution and 7 ml of water. Filtration through celite, followed by evaporation of the solvent, yields an oily product which is used as it is in the following stage.
