Reaction Steps

Method 2 of Example 49 was followed using 3-amino-N-(4-((S)-3-aminopiperidin-1-yl)pyridin-3-yl)-6-(3-(benzyloxy)-2,6-difluorophenyl)-5-fluoropicolinamide with 20 wt % Pd/C in methanol (0.1 M solution). The Boc protected product was purified by preparative HPLC. After volatile materials were removed, the crude material was stirred in 30% TFA in dichloromethane. After volatile materials were removed in vacuo, 3-amino-N-(4-((S)-3-aminopiperidin-1-yl)pyridin-3-yl)-6-(2,6-difluoro-3-hydroxyphenyl)-5-fluoropicolinamide was obtained by preparative HPLC. LCMS (m/z): 459.2 (MH+); LC Rt=2.10 min.
