A mixture of Example 271 (30.6 mg, 0.044 mmol), N,N-diisopropylethylamine (35 μL, 0.20 mmol), 2-piperidin-1-ylethylamine (14.3 μL, 0.10 mmol), and DMF (1 mL) was treated sequentially with 0.5M (0.09 mL) of HBTU in DMF and 0.5M (0.09 mL) of HOBT in DMF. The reaction was stirred for 24 hours at ambient temperature and partitioned between 1N NaOH and ethyl acetate. The combined extracts were dried (Na2SO4), filtered, and concentrated to provide the desired product (20.4 mg, 0.034 mmol). LCMS m/e 609.2; retention time: 2.93 min.
