Reaction Conditions

Reaction Steps

503 mg (1.86 mmol) of the compound from Example 80A and 75 mg (0.34 mmol) of indium(III) chloride were added to 300 mg (1.69 mmol) of the compound from Example 8 in 15 ml of toluene. The reaction mixture was stirred at 80° C. for 5 h, a further 187 mg (0.85 mmol) of indium(III) chloride were added, and the mixture was again stirred for 5 h. After cooling to RT, the reaction solution was mixed with water and ethyl acetate, and the solid was filtered off. The phases of the filtrate were separated, and the aqueous phase was extracted with ethyl acetate. The combined organic phases were dried over sodium sulfate, filtered and concentrated. Purification of the crude product by preparative HPLC (mobile phase: acetonitrile/water gradient) resulted in 107 mg (15% of theory) of the title compound.
