Pyridine → N-(3,4-Dimethoxy-phenyl)-N'-methyl-2-phenyl-N-[2-(4-trifluoromethyl-phenyl)-ethyl]-malonamide

Participants

Reaction Steps

A mixture of 16.2 mg (0.033 mmol) N-(3,4-Dimethoxy-phenyl)-2-phenyl-N-[2-(4-trifluoromethyl-phenyl)-ethyl]-malonamic acid, 15.5 mg (0.049 mmol) methylamine (commercially available), 13.8 mg (0.043 mmol) TBTU and 7.8 mg (0.09 mmol) pyridine in 2 mL DMF was shaken for 4 h at room temperature. The mixture was evaporated to dryness, taken up in methanol, formic acid and subjected to purification by preparative HPLC on reversed phase eluting with a gradient formed from acetonitrile, water and acetic acid. The combined product fractions were evaporated to dryness to yield 2.7 mg (16%) of the title compound. MS(m/e): 501.3 (MH+), MH+ found: 501.3.
