The title compound was prepared in an analogous fashion to that described in Example 29 using 5-bromo-N-(4-(chlorodifluoromethoxy)phenyl)-6-((3S,4S)-3,4-dihydroxypyrrolidin-1-yl)nicotinamide (Stage 46.1) and (1-(tert-butoxycarbonyl)-5-cyano-1H-pyrrol-2-yl)boronic acid (Stage 29.1) to afford a rose solid. UPLC-MS (Condition 3) tR=0.97 min, m/z=490.0 [M+H]+, m/z=487.9 [M−H]−; 1H NMR (400 MHz, DMSO-d6) δ ppm 3.02 (d, J=11.86 Hz, 2H) 3.46 (dd, J=11.86, 3.55 Hz, 2H) 3.90 (br. s, 2H) 5.09 (d, J=2.93 Hz, 2H) 6.29 (dd, J=3.67, 2.45 Hz, 1H) 7.03 (dd, J=3.67, 2.32 Hz, 1H) 7.34 (d, J=9.17 Hz, 2H) 7.83-7.90 (m, 2H) 8.07 (d, J=2.32 Hz, 1H) 8.76 (d, J=2.32 Hz, 1H) 10.18 (s, 1H) 12.63-12.68 (m, 1H).
