Versuchsvorschrift

Silver trifluoromethanesulphonate (564.86 mg, 2.2 mmol) was added to a solution of (3S)-3-amino-1-methyl-3-[3-[4-[3-(trifluoromethoxy)phenyl]-2-pyridyl]prop-2-ynyl]pyrrolidin-2-one (which may be prepared as described in Description 107) (4.28 g, 10.99 mmol) in MeCN (60 mL) at 40° C. and the reaction was stirred for 18 hours. 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 organic phase was washed with water, dried (Na2SO4) and the solvent evaporated to afford a light brown oil. This was purified using an Isolera, with a (50+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-[3-(trifluoromethoxy)phenyl]-2-pyridyl]-1,7-diazaspiro[4.4]non-1-en-6-one (D108) (3.17 g, 8.1414 mmol, 74.1% yield) as a light brown solid;
