Versuchsvorschrift

To a mixture of morpholine (5.8 g, 66.9 mmol) and TEA (9.3 ml, 66.9 mol) in CH2Cl2 (20 ml) was added dropwise a solution of the product of example 82 (5.0 g, 22 mmol) in CH2Cl2 (10 ml) at 0° C. After stirring at room temperature for one hour, the mixture was diluted with CH2Cl2, washed with water, dried and concentrated under reduced pressure. The resulting residue was purified by column chromatography (PE/EA=10/1) to give the titled compound (5.53 g, yield 90.3%).
