Procedure

To a solution of (R)-6-benzyl-2-chloro-4-(4-methoxy-3,3-dimethylpiperidin-1-yl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine (5.04 g, 12.6 mmol) in 1,4-dioxane (100 mL) was added 3,5-dimethyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1-tosyl-1H-indazole, Example 3, (6.16 g, 12.6 mmol), Pd(Ph3P)4 (2.18 g, 1.89 mmol) and a 2 M solution of sodium carbonate (18.9 mL, 37.7 mmol). The reaction mixture was heated at 100° C. under a nitrogen atmosphere for 16 h. The reaction mixture was then allowed to cool to rt and was diluted with EtOAc and water. The layers were mixed and then separated. The organic layer was washed with water and then brine. The separated organic layer was then dried over sodium sulfate, filtered and concentrated. The residue was then purified via FCC (0-70% EtOAc/heptane) to give the title compound. MS (ESI+) m/z 665.6 (M+H)+.
