At room temperature, 8.9 g (22.68 mmol) of rac-cyclopentyl{-4-[(5-oxo-2-phenyl-5,6-dihydro-4H-1,3,4-oxadiazin-4-yl)methyl]phenyl}acetic acid were stirred with 63.6 ml (871.5 mmol) of thionyl chloride for 2 h. The reaction solution was then warmed to 50° C. and stirred for a further 2 h. After the reaction had gone to completion, the reaction solution was freed from the thionyl chloride under reduced pressure. This gave 7.7 g (18.74 mmol, 82% of theory) of the title compound as a colorless oil, which was used without further purification in subsequent reactions.
