Versuchsvorschrift

36 μL (0.47 mmol) cyclopropanecarbaldehyde are added to a solution of 100 mg (0.24 m mol) (2-{5-[5-(4-chloro-phenyl)-pyridin-2-ylethynyl]-indol-1-yl}-ethyl)-cyclopropylmethyl-amine in 20 mL MeOH at RT and 15 min later 59 mg (0.94 mmol) NaBH4 and one drop of glacial acetic acid are added. The mixture is stirred for 1 h at RT, evaporated down i.vac., the residue is taken up in dilute K2CO3 solution, extracted exhaustively with EtOAc and dried over Na2SO4. After the desiccant and solvent have been eliminated the residue is triturated with PE, suction filtered and dried.
