A mixture of 5,6-dichloro-N-(4-(trifluoromethoxy)phenyl)nicotinamide (prepared from 5,6-dichloronicotinic acid in an analogous fashion to that described in Stage 12.2, 1.5 g, 4.27 mmol), (R)-pyrrolidin-3-ol (447 mg, 5.13 mmol), iPrOH (10 mL) and DIPEA (1.104 g, 8.54 mmol) were subjected to MW irradiation at 140° C. for 60 min. The RM was quenched with water (100 mL) and extracted with EtOAc (3×100 mL). The combined organic extracts were washed with brine (100 mL), dried over MgSO4, filtered and the filtrate was evaporated off under reduced pressure to afford the title compound as a beige powder. 1H-NMR (400 MHz, DMSO-d6) δ ppm 1.85-1.97 (m, 2H) 3.59 (d, J=12 Hz, 1H) 3.7-3.8 (m, 1H) 3.8-3.95 (m, 2H) 4.35-4.40 (m, 1H) 5.00 (s, 1H) 7.35 (d, J=2 Hz, 2H) 7.86 (d, J=2 Hz, 2H) 8.17 (s, 1H) 8.66 (s, 1H) 10.22 (s, 1H).
