[1-(4-biphenylyl)-2-(1-pyrrolidinyl)ethyl]methylamine (50 mg, 0.18 mmol) was added to a solution of N-(3,4-dichlorophenyl)-N-methylglycine (49 mg, 0.21 mmol), (benzotriazol-1-yloxy) tris(dimethylamino) phosphonium-hexaflurophosphate (BOP) (118 mg, 0.27 mmol) and triethylamine (TEA) (54 mg, 0.54 mmol) in dichloromethane (DCM) (2.0 mL), The reaction mixture was stirred at room temperature for 3 h and was then concentrated in vacuo. To the residue was added 4 mL of saturated solution of Na2CO3 and then extracted by ethyl acetate (2×3 mL). The combined organic layers were concentrated in vacuo to give a brown solid, which was purified by using a Gilson preparative HPLC system (Phenomenex 75×30 mm column, 40 mL/min flow rate, A: 0.1% TFA in acetonitrile B: 0.1% TFA in water, A: 10 to 100% over 15 min, UV detection at 215 nm) to yield the title compound (52 mg, 58%). MS (ES) m/e 496 [M+H]+.
