Reaction Steps

4-(2-Benzyloxy-4-methoxyphenyl)-pyrrolidin-2-one (2.0 g. 6.8 mmol), potassium phosphate (2.56 g, 1.8 eq), and 3-bromobenzonitrile (1.82 g, 1.5 eq) was added to a flask under N2. The mixture was charged with 10 mL DMF and 10 mL dioxane followed by the addition of 1,2-trans-cyclohexanediamine (100 μL) and CuI (180 mg). The mixture was heated at 110° C. for 20 h and cooled down to r.t. Next the mixture was diluted with 150 mL EtOAc, washed with sat. NH4Cl, water, and brine, and then dried. After concentration, the residue was purified on silica gel (EtOAc:Hexane=3:1) to give 2.2 g of the desired product. Yield: 81%.
