Procedure

2.12 g (32.5 mmol) of potassium cyanide were added to 6.90 g (16.3 mmol) of the compound from Example 52A in 345 ml of DMF. The mixture was stirred at 80° C. for 4 h and then concentrated, and the residue was taken up in ethyl acetate, washed with saturated aqueous sodium bicarbonate solution, water and saturated aqueous sodium chloride solution, dried over magnesium sulfate, filtered and concentrated. The residue was purified by flash chromatography on silica gel (mobile phase: toluene/ethyl acetate gradient). 5.05 g (87% of theory) of the target compound were obtained.
