To 200 mg (0.52 mmol) 4-(7-Chloro-isoquinolin-6-ylsulfanyl)-piperidine-1-carboxylic acid tert-butyl ester (274) dissolved in 5 ml THF and 1 ml NMP were added 20 mg (0.055 mmol) Ferric (III) acetylacetonate. To the red solution 0.3 ml of propylmagnesium-chloride (2M in THF) were added and 2 min stirred at RT. 1 ml 1N HCl and 20 ml diethyl ether were added and the organic layer was washed with brine. The organic phases were dried over Sodium sulfate and evaporated. The residue was purified by HPLC. 85 mg of 4-(7-Propyl-isoquinolin-6-ylsulfanyl)-piperidine-1-carboxylic acid tert-butyl ester could be obtained as the trifluoroacetate.
