Procedure

25 μl (0.229 mmol) of 3-hydroxy-N-methylpyrrolidine are initially charged in 0.5 ml of THF, the mixture is cooled to 0° C., 249 μl (0.249 mmol) of phosphazene base P(4)-t-Bu (1M in THF) are added and the mixture is stirred at this temperature for 10 minutes. 120 mg (0.208 mmol) of the compound from Example 3A are then added, and the mixture is stirred at RT overnight. The reaction mixture is then purified by preparative HPLC (addition of 0.15% hydrochloric acid). This gives 38 mg of the impure target compound. This is dissolved in dichloromethane and washed twice with 1N hydrochloric acid, once with water and once with saturated aqueous sodium chloride solution. After drying over sodium sulphate, the organic phase is concentrated on a rotary evaporator and the crude product is purified once more by preparative HPLC (addition of 0.15% hydrochloric acid).
