Versuchsvorschrift

24 mg (61 μmol) of the compound of Example 1 were initially charged in 1 ml of dimethylformamide, and about 2.7 mg (70 μmol) of sodium hydride (60% in mineral oil) were added. The resulting mixture was stirred at RT for 10 min, 6 μl (9 μmol) of iodomethane were then added and the reaction was stirred overnight. 0.5 ml of 1N hydrochloric acid was added, and the entire mixture was separated by HPLC (Method 5). The appropriate fractions were concentrated on a rotary evaporator, and the residue was dried under high vacuum. This gave 8 mg (32% of theory) of the target compound.
