Reaction Steps

100 mg (0.255 mmol) of the compound from example 28 were dissolved in 5 ml of dimethylformamide, and 49 mg (0.357 mmol) of potassium carbonate were added. The mixture was heated to 70° C. for 10 min and, after cooling, 18 μl (0.291 mmol) of iodomethane were added and the mixture was stirred at RT for 48 h. The mixture was concentrated and the residue was taken up in water and acidified with acetic acid. A solid precipitates out, which was filtered off and washed with water. The purification was effected by means of preparative HPLC (eluent: methanol/water, gradient 30:70→90:10). 18 mg of the title compound were obtained (17% of theory).
