Методика
46 mg (1.22 mmol) of lithium aluminum hydride are initially charged in 8.0 ml of THF and cooled to 0° C. A solution of 161 mg (0.61 mmol) of the compound from Example 26A in 2.5 ml of THF is then added dropwise. The mixture is stirred at RT for 2 h. The reaction solution is then once more cooled to 0° C., and 0.2 ml of water and 0.4 ml of 1 N aqueous sodium hydroxide solution are added. The mixture is stirred at RT overnight. The precipitate formed is filtered off, and the filtrate is freed from the solvent using a rotary evaporator. The residue is used without further purification in the subsequent reaction.
