A mixture of 6-chloro-N-(4-(chlorodifluoromethoxy)phenyl)-5-(5-(dimethylcarbamoyl)-1H-pyrrol-2-yl)nicotinamide (Stage 73.1, 60 mg, 0.102 mmol), (R)-pyrrolidin-3-ol (17.82 mg, 0.205 mmol), DIPEA (71.5 μL, 0.409 mmol) and iPrOH (205 μL) in a sealed vial was subjected to MW irradiation at 140° C. for 1 h. The RM was purified by preparative SFC (Column NH2, isocratic 24% in 6 min.) to yield the title compound as a white solid. UPLC-MS (Condition 3) tR=1.03 min, m/z=520.1 [M+H]+, m/z=564.2 [M+FA−H]−; 1H NMR (400 MHz, DMSO-d6) δ ppm 1.69-1.78 (m, 1H) 1.78-1.89 (m, 1H) 2.96 (d, J=11.74 Hz, 1H) 3.13 (br. s, 6H) 3.25-3.31 (m, 2H) 3.38-3.51 (m, 1H) 4.20 (br. s, 1H) 4.86 (d, J=2.57 Hz, 1H) 6.11-6.21 (m, 1H) 6.57-6.66 (m, 1H) 7.33 (d, J=9.17 Hz, 2H) 7.82-7.92 (m, 2H) 8.04 (d, J=2.45 Hz, 1H) 8.71 (d, J=2.45 Hz, 1H) 10.15 (s, 1H) 11.66 (br. s, 1H).
