Procedure
In a 25 mL sealed tube, 5-chloro-2,3-dihydro-isoindol-1-one (801 mg, 4.8 mmol), 4-bromo-6,7-dihydro-5H-[2]pyrindin-7-ylamine (intermediate B-18 [C], 937 mg, 4.4 mmol), CuI (200 mg, 1.1 mmol), Cs2CO3 (3.0 g, 9.2 mmol) and (+)-(S,S)-1,2-diaminocyclohexane (0.4 mL, 3.2 mmol) were dissolved in dioxane (16 mL). The resulting reaction mixture was heated at 150° C. for 3 hours before it was poured into H2O (50 mL) and extracted with EtOAc (2×125 mL). The organic layer was washed with brine, dried over anhydrous Na2SO4, filtered and concentrated in vacuo to give a crude product which was purified by silica gel flash chromatography (30-100% EtOAc-hexane gradient) to yield the title compound (1.02 g, 80%) as a light yellow solid. MS: 300.2 (M+H+).
