実験手順

Copper Iodide (149.46 mg, 0.7800 mmol), followed by PdCl2(Ph3P)2 (275.41 mg, 0.3900 mmol) was added portionwise to a solution of 2-iodo-4-methyl-6-[4-(trifluoromethyl)phenyl]pyrimidine (4 g, 10.99 mmol) (which may be prepared as described in Description 6), tert-butyl N-[(3S)-1-methyl-2-oxo-3-prop-2-ynyl-pyrrolidin-3-yl]carbamate (1.98 g, 7.85 mmol) (which may be prepared as described in Description 4) and Et2NH (4.06 mL, 39.24 mmol) in THF (50 mL) under N2 and the reaction was stirred at 20° C. for 18 hrs. The solvent was evaporated and the residue was suspended in EtOAc and washed with water/sat. aq. NaHCO3. The organics were collected, dried (Na2SO4) and the solvent evaporated to afford a brown oil. This was purified using a Biotage SP4, with a 100 g SNAP cartridge, eluting with 50 to 100% EtOAc/i-hexane to afford tert-butyl N-[(3S)-1-methyl-3-[3-[4-methyl-6-[4-(trifluoromethyl)phenyl]pyrimidin-2-yl]prop-2-ynyl]-2-oxo-pyrrolidin-3-yl]carbamate (D7) (4.09 g, 8.3726 mmol) as a pale yellow foam;
