الإجراء التجريبي

5.0 g (15.19 mmol) of the crude product 402 are treated with 7.42 g (22.77 mmol) of cesium carbonate in 100 ml of DMF under a nitrogen atmosphere. After 30 min, 3.87 ml (22.77 mmol) of 1-iodopropane are slowly added dropwise and the mixture is then stirred at RT for 18 h. After customary work-up, 5.64 g (100%) of 403 are thus obtained as an oil, which is employed directly in stage 4.
