Procedure
The product from Example 11, Part D (100 mg, 0.3 mmol) and 2-aminopyridine (43 mg, 0.45 mmol) were converted to the title compound in a manner analogous to the method described in Example 7, Part E, using CH2Cl2 in place of THF in the reaction and EtOAc in the workup, and without crystallization (39 mg, 32%). 1H NMR (300 MHz, CDCl3) δ 8.11 (m, 3H), 7.67 (m, 2H), 7.44 (m, 1H), 7.31 (m, 2H), 7.19 (t, J=8 Hz, 1H), 7.00 (t, J=7 Hz, 3H), 5.28 (d, J=15 Hz, 1H), 4.69 (m, 1H), 4.22 (d, J=15 Hz, 1H), 2.54 (m, 2H), 1.96 (m, 2H). MS: m/z (MH+) 408.
