A mixture of (1R,2R,4R) and (1S,2S,4S)-4-(2-chloro-benzenesulfonyl)-2-hydroxy-cyclopentanecarboxylic acid methyl ester (80 mg, 0.251 mmol, example 48, step 5), 1-(bromomethyl)-4-methylbenzene (232 mg, 1.25 mmol) and silver(I) oxide (116 mg, 0.502 mmol) in DCM (2 ml) was stirred at room temperature for 60 h. The reaction mixture was filtered through a pad of Celite, the pad was washed with DCM and the filtrate was evaporated. The remaining grey oil was purified by silica gel chromatography (heptane/EtOAc 80:20-70:30) to obtain the title compound (63 mg, 56%) as colorless oil. MS (EI): 423.1 (M+H)+.
