Procedure

(Z)-3-Methyl-1-(5-methyl-3-(2,2,3,3-tetrafluoro-2,3-dihydrobenzo[b][1,4]dioxin-6-yl)thiazol-2(3H)-ylidenecarbamoyl)-1H-imidazol-3-ium iodide (Example 81A, 250 mg, 0.45 mmol), (R)-3-fluoropyrrolidine hydrochloride (62 mg, 0.49 mmol) and Hunig's base (0.078 mL, 0.45 mmol) in acetonitrile (5 mL) were stirred at 55° C. for 3 hours. The reaction mixture was then cooled to 30° C. with continued stirring for 12 hours. The mixture was evaporated to dryness and purified by reverse phase HPLC to give the title compound. 1H NMR (CDCl3) δ ppm 2.00 (2H), 2.20 (3H), 3.35-3.85 (4H), 5.10-5.30 (1H), 6.60 (1H), 7.20 (1H), 7.35 (1H), 7.45 (1H); MS (ESI) m/z 436(M+H)+.
