Reaction Steps

A mixture of Example 272 (50 mg, 0.12 mmol), N,N-diisopropylethylamine (90 μL, 5.1 mmol), 4-piperidinamine (0.24 mmol), and DMF (2.5 mL) was treated sequentially with 0.5M HBTU in DMF and 0.5M HOBt in DMF. The reaction was stirred for 18 hours at ambient temperature, diluted with water, and extracted with ethyl acetate. The combined organic extracts were dried (Na2SO4), filtered, and concentrated. The residue was purified using normal or reverse phase chromatography. LCMS m/e 581.3; Rt=2.67 min.
