Participants

Conditions

Temperature: 100 °C

Procedure

500 mg (0.980 mmol) of the compound from example 82A were dissolved in 10 ml of DMF, 414 mg (1.270 mmol) of cesium carbonate and 259 mg (1.08 mmol) of 4-(2-iodoethyl)morpholine were added and the mixture was stirred at RT for 18 h, at 40° C. for 18 h and at 100° C. for 8 h. After cooling, water was added and the mixture was extracted with ethyl acetate. The combined organic phases were dried over sodium sulfate and concentrated on a rotary evaporator. The purification was effected by means of preparative HPLC (eluent: methanol/water, gradient 30:70→90:10). 102 mg (17% of theory) of the title compound were obtained.
