Reaction Conditions

Reaction Steps

Lithium aluminium hydride (50 mg) was suspended in ether (2 ml) and the suspension was cooled to 0° C. To the suspension was added dropwise a solution of the compound 13-2a (167 mg) prepared by Step 1 in ether (2 ml) and the mixture was refluxed for 2 hours. After the completion of the reaction, the reaction solution was basified with 5 N aqueous sodium hydroxide solution. Then, aqueous Rochel solution was added thereto and stirred for 1 hour, at room temperature. Then, resulting mixture was extracted with ether (50 ml×3) and concentrated under reduced pressure to yield the compound 13-3a (120 mg, 71%). The following Step 3 was proceeded using the compound 13-3a which was not purified.
