By the method described in Example 5, the title compound of Example 4 (0.5 g, 1.5 mmol) in 20 mL of CH2Cl2 was converted to its mixed anhydride with NMM (0.16 mL, 1.5 mmol) and IBCF (0.2 mL, 1.5 mmol). This intermediate was condensed with 4-aminopyridine (0.21 g, 2.25 mmol) to produce the title compound (94 mg).
