Reaction Steps

The title compound was prepared by treating (1R,6S)-3-[(3-bromopyridin-2-yl)carbonyl]-8-(4,6-dimethylpyrimidin-2-yl)-3,8-diazabicyclo[4.2.0]octane (30 mg, 0.08 mmol), with 1H-1,2,3-triazole (43 uL, 0.75 mmol), Cs2CO3 (49 mg, 0.15 mmol), CuI (3.5 mg, 0.02 mmol), and (R,R)-(−)-N,N′-dimethyl-1,2-cyclohexanediamine (12 uL, 0.05 mmol) in 1,4-dioxane containing 3% water. The mixture was heated to 160° C. in a sealed tube. The reaction was purified directly on 16 g SiO2 with 0-2% NH3 MeOH/CH2Cl2 to give partially purified material which was further purified to the individual two isomers, the title compound (2 mg, 4% yield) and Example 183 (10 mg, 10% yield) by reverse phase HPLC. MS (ESI) mass calcd. for C20H22N8O, 390.5; m/z found, 391.2 [M+H]+.
