5-iodo-1-(3-{(1S,5R)-1-[4-(trifluoromethyl)phenyl]-3-azabicyclo[3.1.0]hex-3-yl}propyl)-2,4(1H,3H)-pyrimidinedione (Prep10, 150 mg, 0.282 mmol), copper (1+) iodide (59.1 mg, 0.310 mmol), N,N-dimethylglycine (32.0 mg, 0.310 mmol) and K2CO3 (86 mg, 0.620 mmol) were dissolved in Dimethyl Sulfoxide (DMSO) (2 ml) to give a light blue solution with a white precipitate. To this mixture, 3-(trifluoromethyl)-1,4,6,7-tetrahydropyrano[4,3-c]pyrazole (starting material prepared according to a similar procedure to that described in Prep38 followed by Prep39, 179 mg, 0.931 mmol) was added. After 18 h shaking at 150° C., the reaction mixture was diluted with EtOAc (5 ml) and the organic phase was washed with water (4×10 ml), then brine (5 ml), dried over Na2SO4, then filtered and the solvent evaporated. The obtained crude was passed through an SCX cartridge and eluted with 2M solution of ammonia in MeOH. The resulting mixture was further purified by preparative LC-MS to obtain 9.6 mg of the title compound as a free base.
