Reaction Steps
240 mg of sodium borohydride are added to 120 mg of the compound obtained in Step B above dissolved in 6 ml of isopropanol. The mixture is heated at 50° C. for 10 minutes. The solvent is removed under reduced pressure, then the residue that is obtained is taken up in 5 ml of water. The pH of the solution is adjusted to 4 by addition of 6N hydrochloric acid. The precipitate is collected by filtration, washed with water and dried.
