実験手順

To a solution of the product obtained in Step H (0.2 g) in THF (10 ml) at 0° C. there is added, in portions, lithium aluminium hydride. After stirring for 3 hours at ambient temperature, the reaction mixture is hydrolysed at 0° C. with aq. NaOH solution and water. After filtration, the filtrate is evaporated to dryness and the residue obtained is purified on silica gel (SiO2: gradient CH2Cl2/MeOH with the addition of 1.4N NH3 in the MeOH) to yield the title product, which is used directly in the next Step.
