A mixture of Intermediate 44 (200 mg, 0.938 mmol), 2-(chloromethyl)-6-fluoropyridine (ALLICHEM, 137 mg, 0.938 mmol) and potassium carbonate (ALDRICH, 157 mg, 0.938 mmol) dissolved in acetonitrile (10 mL) was stirred at 80° C. for 6 h. 0.2 eq. of 2-(chloromethyl)-6-fluoropyridine (ALLICHEM, 27.3 mg, 0.188 mmol) and 5 mL of dry acetonitrile were added. Reaction was stirred at 80° C. overnight. Reaction was diluted with DCM and filtered. Solvent was evaporated to dryness. Residue was purified by silica column chromatography using a linear gradient of hexane/EtOAc to yield the title compound (94 mg, 0.292 mmol, 31% yield). 1H NMR (300 MHz, DMSO-d6) δ ppm: 8.02-7.88 (m, 6H), 7.11 (m, 2H), 6.43 (d, 1H), 5.45 (s, 2H). [ES+MS] m/z 323 (MH+).
