Reaction Steps
To a solution of crude (S)-2-((tert-butyldimethylsilyloxy)methyl)pyrrolidine (0.455 g, 2.11 mmol) in toluene (20 mL) were added Pd2(dba)3 (0.039 g, 0.042 mmol) and rac-BINAP (0.066 g, 0.106 mmol). The solution was purged with argon and heated to 85° C. for 10 min. After cooling to room temperature, sodium tert-butoxide (0.406 g, 4.22 mmol) and 3,5-dibromopyridine (0.5 g, 2.11 mmol) were added and the reaction mixture was then heated at 85° C. overnight. The mixture was poured into sat NH4Cl (20 mL) and the aqueous layer was extracted with DCM (2×25 mL). Combined organics were washed with brine, dried over Na2SO4, filtered and evaporated to dryness. The residue was purified by silica gel flash chromatography eluting with a 0 to 5% MeOH-DCM gradient to give the title compound (0.412 g, 53%) as a yellow oil. MS: 371.0, 372.9 (M+H+).
