Reaction Steps

200 mg of the amorphous compound obtained in Example 95 was dissolved in 5 ml of methanol, to the solution was added in portions 35.2 mg of sodium borohydride at a room temperature with stirring, and the mixture was stirred for 2 hours and evaporated to remove the solvent. Resulting residue was applied to a silica gel column and eluted with chloroform/methanol (100:4), to obtain 116 mg of the title compound as pale yellow oil.
