Procedure
3.43 g of the product obtained in Step 4 are dissolved in 55 ml of acetic acid. In the course of 5 minutes, 3.84 g of sodium cyanoborohydride are added in portions to the reaction mixture, which has been cooled to 13° C. After returning to ambient temperature, stirring is carried out for 2 hours, and then the reaction mixture is cooled to 0° C. and the pH is adjusted to 11 by the addition of a solution of sodium hydroxide (45 g in 250 ml of water). The milky solution obtained is extracted with ether. The organic phases are washed, dried and concentrated to yield the expected product.
