Versuchsvorschrift

A solution of the compound obtained in Step e (1.35 g; 293 mmol) in 16 ml of anhydrous toluene is added to a mixture of LiCN (0.5 M in DMF) (11.72 ml; 5.86 mmol), (Ph3P)4Pd (237 mg; 0.205 mmol) and 12-crown-4 (36 mg; 0.205 mmol) under an argon. atmosphere. The reaction mixture is stirred at ambient temperature for 6 hours. Water (10 ml) is added to the reaction mixture, and the organic phase is extracted with diethyl ether. After drying and concentration, the residue obtained is purified on silica gel (eluant:heptane/EtOAc) to yield the title product.
