Versuchsvorschrift

To a solution of (1R,2R,4R) and (1S,2S,4S)-4-(2-chloro-benzenesulfonyl)-2-(4-chloro-phenoxy)-cyclopentanecarboxylic acid methyl ester (30 mg, 0.0699 mmol) in DCM (3 ml) was added trimethylaluminium (175 μl, 2M solution in toluene, 0.349 mmol), triethylamine (29.1 μl, 0.210 mmol) and 1-amino-1-cyclopropane-carbonitrile hydrochloride (21 mg, 0.1757 mmol) and the reaction mixture was stirred at 40° C. overnight. The mixture was then cooled to room temperature, diluted with brine and extracted 3 times with DCM. The combined organic layers were washed with water and brine, dried (Na2SO4) and evaporated. The remaining brown semisolid was purified by silica gel chromatography (DCM/MeOH 100:0-98:2) yielding a yellow solid (5 mg) that was triturated with ether to obtain the title compound (3 mg, 9%) as off-white solid. MS (EI): 477.0 (M+H)+.
