Procedure

Ammonium acetate (1.53 g, 19.8 mmol) was added to a solution of the compound from step 1 (545 mg, 1.98 mmol) in MeOH (8 mL). After stirring at RT overnight sodium cyanoborohydride (149 mg, 2.38 mmol) was added and the reaction was refluxed for 6 h. The solvent was evaporated and the solid, redissolved in ethyl acetate, was extracted with water. The organic layer was separated, washed with brine, dried over sodium sulphate, filtered, evaporated and purified by preparative HPLC. The relevant fractions were lyophilized to give 147 mg (yield: 19%) of the pure product.
