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.
