Procedure

3-(4-(2-Aminopyridin-4-yloxy)-3-fluorophenylamino)-3-oxopropanoic acid (Compound C of Example 102, 30 mg, 0.10 mmol) was coupled with (R)-2-amino-2-phenylacetamide hydrochloride (Bachem, 28 mg, 0.15 mmol) in a manner similar to that which is described in Step C of Example 1 to give (R)—N1-(2-amino-2-oxo-1-phenylethyl)-N3-(4-(2-aminopyridin-4-yloxy)-3-fluorophenyl)malonamide, hydrochloride salt (14 mg, 30% yield). 1H NMR (DMSO-d6) δ 10.65 (s, 1H), 8.76 (d, 1H, J=8.0 Hz), 7.92 (d, 1H, J=7.0 Hz), 7.75-7.88 (m, 4H), 7.20-7.43 (m, 8H), 6.66 (m, 1H), 6.09 (s, 1H), 5.35 (d, 1H, J=8.0 Hz), 3.45 (d, 1H, J=15.0 Hz), 3.37 (d, 1H, J=15.0 Hz); MS(ESI+) m/z 438.23 (M+H)+.
