Triethylamine → N1-[1-(4-biphenylyl)-2-(1-pyrrolidinyl)ethyl]-N2-(3 4-dichlorophenyl)-N1,2-dimethylalaninamide

Participants

Reaction Steps

N-(3,4-dichlorophenyl)-2-methylalanine, lithium salt (100 mg, 0.4 mmol), [1-(4-biphenylyl)-2-(1-pyrrolidinyl)ethyl]methylamine (124 mg, 0.44 mmol), triethylamine (246 uL, 1.77 mmol), and (1H-1,2,3-benzotriazol-1-yloxy)[tris(dimethylamino)]phosphonium hexafluorophosphate (BOP Reagent, 215 mg, 0.486 mmol) were added in that order to a 4 mL screw capped vial that contained 2 mL of anhydrous DMF. The reaction mixture was stirred for 20 hours at room temperature, then filtered through a 0.45 um PTFE Acrodisk, and purified by reverse-phase HPLC (Xterra Prep RP C-18, 30×150 mm, 50 mL/min, A: acetonitrile B: water, pH 10 w/NH4OH, A: 20 to 99% over 9 min, UV detection at 214 nm) to give the title compound as a white solid. MS (ES) m/e 510 [M+H]+.
