Versuchsvorschrift

330 mg (1.1 mmol) of the compound of Example 1A and 212 mg (1.2 mmol) of bromomethylcyclohexane were initially charged in 5 ml of dimethylformamide, 389 mg (1.2 mmol) of cesium carbonate were added and the resulting mixture was stirred at RT overnight. 0.5 ml of 1N hydrochloric acid was added, and the entire solution was separated by HPLC (Method 5). The appropriate fractions were freed from volatile components on a rotary evaporator, and the residue was dried under high vacuum. This gave 60 mg (19% of theory) of the target compound.
