Reaction Steps

In an oven-dried round bottomed flask was added L-proline, 1-[2-(3,4,5-trimethoxyphenyl)-2-oxoethyl] 2-(4-aminophenyl)ethylamide (100 mg, 0.23 mmol), and tetrahydrofuran (5 mL). The solution was stirred at 22° C., and treated with pyridine (0.037 mL, 0.45 mmol, 2.0 eq) followed by acetyl chloride (0.024 mL, 0.34 mmol, 1.5 eq). The reaction mixture was allowed to stir for one hour. The solvent was removed in vacuo and the residue partitioned between EtOAc (50 mL) and sat. NaHCO3 (50 mL). The organic layer was washed with sat. aq. NaCl, dried (MgSO4) and concentrated to an oil. The oil was purified by flash chromatography to provide 70 mg of L-proline, 1-[2-(3,4,5-trimethoxyphenyl)-2-oxoethyl] 2-(4-(N-acetyl)aminophenyl)ethylamide as a foam.
