Reaction Steps

2-(2-Amino-ethoxy)-4-[5-(5-chloro-2-oxo-2H-[1,2']bipyridinyl-5'-ylmethyl)-imidazol-1-ylmethyl]-benzonitrile (L-824,459, 50 mg, 0.11 mmol) was dissolved in CH2Cl2 (550 , μl) and treated with acetic anhydride (208 μl, 0.22 mmol). DIEA was then added until pH=7-8. The reaction mixture was stirred at room temp. for 2 hours. Saturated NaHCO3 was added (10 mL) and the solution was extracted with CH2Cl2 (2×10 mL). The organic layer was washed with brine, dried (MgSO4), filtered, and concentrated to yield the final product.
