Versuchsvorschrift

Silver trifluoromethanesulphonate (358.56 mg, 1.4 mmol) was added to a solution of (3S)-3-amino-1-methyl-3-[3-[4-methyl-6-[4-(trifluoromethyl)phenyl]pyrimidin-2-yl]prop-2-ynyl]pyrrolidin-2-one (2.71 g, 6.98 mmol) (which may be prepared as described in Description 14a) in MeCN (60 mL) at 50° C. and the reaction was stirred for 3 days. Additional AgOTf (10 mol %) was added and stirring was continued for 24 hrs. The solvent was evaporated and the residue was suspended in EtOAc. The organics were washed with water, dried (Na2SO4) and the solvent evaporated to afford a light brown oil. This was purified using a Biotage Isolera with a 100 g SNAP cartridge, eluting with 0 to 100% (mixture of 1% of 2M NH3 in MeOH; 9% MeOH; 90% EtOAc) in EtOAc, affording the (5S)-7-methyl-2-[4-methyl-6-[4-(trifluoromethyl)phenyl]pyrimidin-2-yl]-1,7-diazaspiro[4.4]non-1-en-6-one (D15a) (2.51 g, 6.4626 mmol, 92.6% yield) as a light brown solid. The NMR was the same is as that for the R isomer produced in Description 15 but also contained traces of impurities.
