A stirred solution of 253C (55 mg, 0.127 mmol) in DMF (1.0 mL) was treated with N1,N1-dimethylethane-1,2-diamine (0.021 mL, 0.190 mmol), BOP (72.9 mg, 0.165 mmol) and TEA (0.035 mL, 0.254 mmol), and the reaction mixture was stirred at ambient temperature for 1 hour. The reaction mixture was concentrated, triturated with water, and the resulting white solid was collected by filtration to yield 253D (60.0 mg, 93.7% yield). HPLC: Rt=3.47 min. (PHENOMENEX® Luna C18 4.6×30 mm 3 u, A10-90% aqueous methanol containing 0.1% TFA in 2 min; 4 mL/min flow). MS (ES): m/z=504.1 [M+H]+.
