Reaction Steps
A mixture of tris(dibenzylideneacetone)dipalladium(0) (0.36 g, 0.34 mmol) under nitrogen in toluene (136 mL) was treated with (R)-(+)-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (0.96 g, 1.5 mmol), treated with sodium tert-butoxide (0.98 g, 10 mmol), treated with benzyl amine (1.1 mL, 10 mmol), warmed to 85° C., treated dropwise over 45 minutes with a solution of Example 44B (2.1 g, 6.8 mmol) in toluene (30 mL), stirred at 85° C. for 1 hour and treated with water (50 mL). The organic layer was isolated and the aqueous layer was extracted with ethyl acetate. The combined organic layers were washed with brine, dried (Na2SO4) and concentrated. Purification of the residue on silica gel with 30% ethyl acetate/hexanes provided the desired product.
